Aimed at the problems to improve the confidence in ground clutter simulation for ground-based tracking radar, a simulation method in combination of statistical models with terrain matching is proposed. First, the distribution patterns jammed by ground clutter at amplitude and power spectra in combination of actual deployment position of radar, and in full consideration of the impact of terrain obstruction on radar detection are analyzed, and a database of terrain profiles in various quantification directions, obstruction angles, and geographical features, is established. And then, ground clutter echo signal sequence generated is a match for the detection signal waveform through digital convolution. The simulation results show that this method requires low signal synthesis power, effectively controlling the scale of signal processing, and is still more conformed with the actual working conditions for radar under terrain obstruction.
