基于 DEM的滨海地区非均匀杂波模拟
Modeling of heterogeneous clutter in littoral environment based on DEM
摘要
Abstract
Due to the importance of the military location and complex variability of scene in coastal area,clutter simulation in this area becomes the central part of the radar echo simulation researches.This paper first analyzed the key factors influencing the generation of compound clutters in costal area.Then it divided the terrain scene into units combined with digital evaluation model (DEM).Finally,it established backscattering coefficient model of clutter unit in the junction of land and sea to calculate the radar clutter power spectrum.Simulation results show that the non-uniform power spectral characteristic of airborne PD ra-dar in costal area is more significant undulated,compared with pure sea clutters.The simulation results is in line with theoreti-cal analysis of costal area clutters,demonstrating the practicality and effectiveness of the compound clutter model and power spectral calculating method based on DEMin coastal area.关键词
