Ground Moving Target Trajectory Reconstruction in Single-Channel Circular SAR

Two-channel Sar Ground Moving Target Indication for Traffic Monitoring in Urban Terrain

This paper introduces and analyses a technique that implements CFAR detection and parameter estimation of moving targets in urban terrain. Firstly, it presents a probability distribution to use with the product model. This model helps to account for the extremely high inhomogeneity encountered in urban terrain. Along with the proposed distribution, the paper then discusses the numerical computa...

Moving Target Detection and Trajectory Estimation Using SAR Data

Conventional Synthetic Aperture Radar processing leads to moving targets being imaged displaced from their real positions and blurred. This is mainly due to the used reference phase no longer being valid, including an additional Doppler-shift and a Doppler-spread. Since these effects are not considered in the focusing algorithm, the resulting SAR image shows the moving targets defocused and/or ...

Multiple Moving Target Detection and Trajectory Estimation Using a Single SAR Sensor

| The paper presents a novel methodology for determining the velocity and location of multiple moving targets using a single stripmap synthetic aperture radar (SAR) sensor. The so-called azimuth position uncertainty problem is therefore solved. The method exploits the structure of the amplitude and phase modulations of the returned echo from a moving target in the Fourier domain. A crucial step...

Techniques for ground moving target detection and velocity estimation with multi-channel Synthetic Aperture Radars (SAR)

An Airborne Sar Experiment for Ground Moving Target Identification

With the launch of the advanced high resolution radar satellite TerraSAR-X in summer 2006 new possibilities open to demonstrate traffic monitoring from space. At the German Aerospace Center an automatic and operational traffic processor is developed for the TerraSAR-X ground segment. This comprises the detection of moving objects in Synthetic Aperture Radar (SAR) images, their correct assignmen...
