Effective registration of Synthetic Aperture Radar(SAR)image before and after noise jamming is the basis for judging the jamming degree and for calculating image correlation,which is also a basis for evaluating the countermeasure effect of SAR.

An algorithm for reducing speckle noise on the synthetic aperture radar(SAR) image is presented based on the spatial oriented tree(SOT) structure in a Contourlet domain.

Synthetic aperture radar(SAR)image has some common features such as huge data volume,relative complex algorithm.

Synthetic aperture radar(SAR) has become one of the important tools to map the shallow water bottom topography.

The simulation system of the detection of ground vehicle by SAR(Synthetic Aperture Radar) sensor was proposed.

According to the electromagnetic backscattering theory, a synthetic aperture radar (SAR) raw signal simulation for building was proposed.

Based on the different locationsof the vibrator, the distribution of SAR value within the horizontal and vertical plane at the center of tumor globe is calculated respectively.
