Merna Baharuddin (Indonesia), Ph.D. Thesis, "Development of microstrip
antenna for circularly polarized synthetic aperture radar " (Doctor
of Engineering) *** [Download Thesis]
Abstract :
Synthetic aperture radar (SAR) is an active sensor that can
produce high resolution imagery in microwave bands. The use of microwave
frequencies enables penetration through clouds, and even through forest canopy
for lower frequency bands. A circularly polarized SAR (CP-SAR) to be launched onboard a micro-satellite
is currently developed in the Microwave Remote Sensing Laboratory (MRSL)
of the Center for Environmental Remote Sensing (CEReS), Chiba University.
As part of the project, an airborne CP-SAR development is also undertaken
in order to obtain sufficient knowledge of CP-SAR sensor systems. An L-band
CP-SAR system will be designed for operation onboard an unmanned aerial
vehicle (UAV).
Conventional SAR systems have been based on linearly polarized (LP) antenna
systems. However, there are limitations due to the propagation phenomena
such as the variation of geometric distance between the radar system and
the Earth, the occurrence of a phase shift when microwave strikes smooth,
reflective surfaces, etc. Especially for space propagation, electromagnetic
waves propagating through the ionosphere interact with electrons and magnetic
fields. As a result, the polarization vector of the electric field is tilted
by the Faraday rotation effect.The destructive effects mentioned above of a SAR sensor with linear polarization
can be solved by the use of CP-SAR. The operational frequency is chosen
to be 1.27 GHz in L-band considering its superior features on particular
applications. To investigate the new SAR sensor with CP antennas, in this
dissertation, CP microstrip elements are proposed and developed to be implemented
in an array antenna for the CP-SAR sensor onboard an UAV. The numerical
simulations and the measurement results are shown and discussed. |

Luhur Bayuaji (Indonesia", Ph.D Thesis, "Application of differential
interferometry synthetic aperture radar data to disaster monitoring"
(Doctor of Engineering) *** [download thesis]
Abstract :
Disasters, both natural and man-made, are increasing in their frequency
and catastrophic impact in Indonesia. Earthquake, flood, landside, subsidence
are only a few to mention. Disaster, in the true sense, always occur involving
human beings, especially as victims. Due to the lack or inadequate disaster
prevention and mitigation strategies in Indonesia, the impact of disasters
which they do occur is much greater than in other developed countries.
Disaster detection and monitoring are essential aspect in disaster mitigation
and it’s conventionally done by ground survey. Nowadays, remote sensing,
both in optical and radar sensor, plays important role on disaster mitigation.
In tropical region such as Indonesia, data retrieved by radar sensor provide
some information which hard to obtain by optical sensor. Radar interferometry
is an imaging technique for measuring the geodetic information of terrain
by exploiting phase information of the backscattered radar signal from
ground surface to retrieve the altitude or displacement of the objects.
Differential Interferometry Synthetic Aperture Radar (DInSAR) is one of
well known the radar interferometry techniques that allow us to investigate
surface deformation phenomena with a centimeter to millimeter accuracy
and with a large spatial coverage. It has been increasing used to monitor
ground surface displacements, which may be caused by various natural disasters
such as earthquakes, landslides, avalanches or human activities such as
mining activities, groundwater extraction, etc. Typically, ii displacement
information was being collected through field measurement which has many
disadvantages such as time consuming, hazardous and few point locations.
This dissertation will reveal the ability and advantages of DInSAR as efficient
and cost-effective method for subsidence disaster monitoring in tropical
area which were caused by natural disaster and human activities. In this
dissertation, DInSAR will be integrated with ground survey data and Geographic
Information System (GIS) to provide better result and analysis. In the
future, further development of this dissertation is to create integrated
system to reinforce subsidence assessment method and mitigate potential
risk to infrastructure, live and environment. The study sites in this dissertation
are Jakarta, the capital city of Indonesia for urban disaster monitoring
and Sidoarjo, east Java province for man-made disaster monitoring. Jakarta
has serious subsidence problem which give impact to infrastructure and
worsening flood impact every year. Sidoarjo experiences subsidence because
of continuous and enormous volume of geological hot mud eruption which
is triggered by gas exploration drilling. Both sites have similarities
that the subsidences are caused by natural and human activities. The selection
of suitable interferometric pairs is limited by temporal separations of
the acquired SAR images as well as the characteristics of the iii site.
The pairs with good coherence were selected for further processing. The
coherence analysis was studied for each site. The Digital Elevation Model
(DEM) data retrieved from Shuttle Radar Topography Mission were employed
to remove the topographic error. Phase unwrapping process was employed
in the DInSAR result. In this study the subsidence areas were retrieved
and analyzed by using L-Band ALOS PALSAR data.The influence of coherence
on DInSAR result also presented in this study. Atmospheric and temporal
error occurred in the result were analyzed and raised the importance to
increase the data availability and revisit cycle. For Sidoarjo study site,
hot mud temperature distribution was investigated using TERRA ASTER data.
Based on DInSAR result, simple method to estimate subsidence volume also
developed in this study because volume of subsidence gives direct impact
for infrastructure and environment. Subsidence direction and subsidence
potential area also investigated by calculating subsidence gradient of
continues monitoring. It leads to possibility on producing subsidence hazard
map on investigated area. The result of this study showed that the DInSAR
method was potential to monitor subsidence in urban area as well as vegetated
area. The accuracy of the derived subsidence can be further improved by
increasing the data availability and shorten revisit cycle. Better imaging
resolution will also be iv advantage. The subsidence can be monitored at
an accuracy of centimeter in the wavelength 24 cm of L-Band ALOS PALSAR. |

Polarized Synthetic Aperture Radar System for Unmanned Aerial Vehicle and

(Supervisor : Josaphat Tetuko Sri Sumantyo)
Abstract :
合成開口レーダ（SAR）は夜昼間かつ全天候型センサで、地球環境の観測に多く用いられてきた。従来のSARセンサでは直線偏波による水平・垂直偏波を用いており、電離層を通過する際、ファラデー効果による偏波面の回転や衛星の姿勢によって後方散乱信号の品質が低下した。また、プラットフォームが大型となり、消費電力の抑制も難しかった。こうした様々な問題を解決するために、本研究では無人航空機（UAV）および小型衛星搭載用の円偏波SARセンサの開発に向けて、理論的考察および数値シミュレーションを行った。円偏波SARのパラメータとして、動作周波数1.27GHzの付近における通常の3
dBビーム幅に対して、新たに3 dB軸比ビーム幅の概念を導入し、これらのパラメータとアンテナビーム幅およびアンテナ形状との関係について詳細に考察した。小型衛星搭載の円偏波SARの場合、これらのパラメータに対して、地上観測幅やパルス繰り返し周波数などの影響も検討した。その結果、最適な軸比ビーム幅を選択することによって、直線偏波SARの場合と比較して、CP-SARがより小型のアンテナで実現できることが明らかとなった。本研究により、UAVおよび小型衛星搭載の円偏波SARの実現が十分に可能であることを実証するとともに、同装置の設計開発に向けて不可欠な指針を示すことができた。

Prilando Rizki Akbar Development of Circularly Polarized Synthetic Aperture
Radar (CP-SAR) for Small Satellite : Preliminary Design" (Master of
Engineering) [Download Thesis] ****
Abstract :
For decades, Synthetic
Aperture Radar (SAR) has been developed and implemented by many research
institutions and national aerospace agen-cies. Comparing to other available
sensors (opti- cal sensor), this SAR can be operated in all day-night time and
weather condition. And also through its high resolution and its polarization
characteristic, made this sensor technology beco-me more suitable for Earth
observation appli-cations. In the previous SAR systems only linear polarization,
both vertical and horizontal pola-rization, were in used. Therefore it is very
sensi-tive to the Faraday rotation effect and platform posture, which it will
be contributed to resulted image quality; high power consumption and bulky size
in the sensor system. Thus to solving this problem, currently an L-band (1.27
GHz) SAR with circular polarization is being researched and developed and in
our laboratory. Firstly, this new L-band Circularly Polarized Synthetic
Aperture Radar (CP-SAR) will be developed for ground measurement experimental.
Then it is planned to employ this CP-SAR on an airborne and spaceborne
platform. The Unmanned Areal Vehi-cle (UAV) and a small satellite (less than 60
Kg) will be use as the airborne platform and the spaceborne platform
respectively. In this thesis, the conceptual design of CP-SAR onboard small
satellite will be discussed. It will be started from CP-SAR onboard small
satellite structure and system and then goes further in to the details of its
preliminary spaceborne SAR parameters design.
Also, the current research result of CP-SAR hard-ware development also will be presented. It consists of L-band CP SAR circuit system design, software simulation and its hardware implementation. |

Aperture Radar (円偏波合成開口レーダ用チャープパルスのシミュレーション) (Master of Engineering) ***
Abstract :
本研究では無人航空機と小型衛星に搭載する円偏波合成開口レーダのチャープパルスの発生器をシミュレーションする。無人航空機用のチャープパルスの仕様として、バンド幅125
MHzとパルス長10μSである。また、小型衛星の仕様が10 MHzと10μSである。このチャープパルスを発生させるために、VHDLプログラミング言語によるDDSアルゴリズムでプログラミングをした。正弦波のルックアップテーブルを再現するために、ここで、第1
QuadrantアルゴリズムがDDSのルックアップ内に使用された。そのため、4分の1のルックアップテーブルで、波形を最小限の目盛りで再現することができた。チャープパルスのパラメータもDDS方程式の初期値で設定で設定することもできた。VHDLプログラムのシミュレーションの出力ファイルでは、チャープパルスの情報を示す。そして、数値計算プログラミング言語によって、このファイルを読み込んで、チャープパルスのバンド幅、パルスの時間幅、波形などを表示させる。この情報がVHDLプログラムでFPGAボードに書き込んで、合成開口レーダの送信機に接続する予定である。これから、この研究成果が当センターの無人航空機搭載の円偏波合成開口レーダシステムに入れ込む予定である。New ! |
