Abstract

Simulation of the sea clutter signal by using digital signal processing (DSP) platform for radar performance testing is an prospective and widely used technique in radar engineering application. Based on the digital signal processor TMS320C6748 as the hardware platform and the autoregressive model, a method of generating non-stationary K distributed sea clutter is proposed. In DSP realization of the non-stationary sea clutter sequence simulation, its amplitude usually satisfies the K distribution, and the amplitude envelope and Doppler spectral center frequency will change with time. The simulation results show that the probability distribution and time-frequency characteristics of the sea clutter are in good agreement with the theoretical values.
