Abstract :
This paper investigates how relative speed estimation of moving targets in synthetic aperture radar (SAR) images is affected by strong stationary surrounding clutter. The result extends previous work by estimating moving target relative speed under the influence of clutter and Gaussian noise. The results obtained show that good estimates can be obtained even in situations with relatively high clutter and noise, i.e. SNR and SCR lower than 10 dB.
