Abstract

The Doppler performance of MMW Costas frequency-hopping (FH) radar was analyzed briefly. By defining waveform entropy for the 1D range profile of this radar, motion compensation was converted into a 1D optimization problem. Based on simulated annealing algorithm (SAA), a 1D search algorithm was presented and applied to motion compensation of Costas FH radar. Simulations show that this method is robust and globe. Satisfying results can be obtained even in the low-SNR case.
