Research on clutter model in simulation design of PD radar system

Abstract

In order to accurately analyze the impact of different backgrounds on radar detection performance in radar system simulation design, this paper combines the average backscattering coefficient and directional propagation factor of ground clutter and sea clutter, establishes a model of the relationship between signal to clutter ratio and grazing angle, and obtains the clutter echo signal power. Finally, the correctness of the model is verified by calculating the influence of clutter on target detection probability.
