Abstract

The problem of estimating 3D velocity for slowly moving target in synthetic aperture radar (SAR) images is addressed. To solve this task, a new scheme based on multi-static SAR is presented. The developed scheme first estimates all values of the Doppler centroid and Doppler frequency rate in multi-static SAR by fractional Fourier transform method. Then, a Doppler frequency rate is used to estimate the cross-range velocity of the moving target. The Doppler centroids are used to estimate the range velocity and height velocity. Simulation results are given to demonstrate the effectiveness of the scheme.
