%X A Costas frequency hopped signal is a high range resolution radar signal, motion compensation is the key technology to realize high range resolution. A waveform entropy method for motion compensation of Costas frequency hopped signal is studied in this paper, and optimization is made in the definition of waveform entropy. Simulation results show that this method is feasible, insensitive to the quadrature demodulation error, and anti-noise to some extent.
