Description: The project of high-resolution synthetic aperture radar system designed for a small satellite
is proposed. It is intended for expeditious producing of detailed radar images of
natural and artificial origin objects. The offered radar system has space resolution of 3
meters and four non-coherent accumulations (looks). The system key feature is, that
images synthesis and their normalization are carried out immediately on the satellite.
The obtained radar image is exposed to compression. These operations reduce volume of
data, transmitted on the ground by tens time. For a data acquisition the antenna of 1-m
diameter could be used. Platform: |

Description: 针对合成孔径雷达(SAR) 图像含有大量斑点噪声的特点,基于Contourlet 的多尺度、局部化、方向性和各向
异性等优点,并结合隐马尔科夫树( HMT) 模型和隐马尔科夫场(MRF) ,提出了一种基于Contourlet 域持续性和聚
集性的SAR 图像模糊融合分割算法。该算法有效捕获了Contourlet 子带的持续性和聚集性,并分别用HMT 和
MRF 来刻画,再依据模糊测度,将多尺度HMT 和MRF 有机融合,建立Contourlet 域HMT2MRF 融合模型,并导
出新模型下的最大后验概率(MAP) 分割公式。对实测SAR 图像进行了仿真,仿真结果和分析表明:与小波域上的
HMT2MRF 融合分割及Contourlet 域上HMT 和MRF 分割算法相比,该算法在抑制斑点噪声的同时,有效地提高
了SAR 图像的分割精度- In view of the speckle noise in the synthetic aperture radar (SAR) images , and based on the Contourlet′s
advantages of multiscale , localization , directionality , and anisot ropy , a new SAR image fusion segmentation
algorithm based on the pe rsis tence and clustering in the Contourlet domain is p roposed. The algorithm captures the
pe rsis tence and clus tering of the Contourlet t ransform , which is modeled by hidden Markov t ree (HMT) and Markov
random field (MRF) , respectively. Then , these two models are fused by fuzzy logic , resulting in a Contourlet
domain HMT2MRF fusion model . Finally , the maximum a poste rior (MAP) segmentation equation for the new fusion
model is deduced. The algorithm is used to emulate the real SAR images . Simulation results and analysis indicate that
the p roposed algorithm effectively reduces the influence of multiplicative speckle noise , imp roves the segmentation
accuracy and p rovides a bet te r visual quality for SAR images ove r the Platform: |

Description: The study of SAR (Synthetic Aperture Radar) image formation using MATLAB it is explained in the following project. The main to use MATLAB in this project was the most important thing to choose it. As MATLAB it is one of the most tools used by engineers, I considered really interesting the project, and moreover with the image treatment that it involved.
The study of this field requires some background information to identify the steps which must be done to obtain some results. SAR images treatment it is quite complex so, we must study all the background that the image formation involves, and learn in MATLAB the main functions which will have to be used. Platform: |
