Embodiment
[0046] The invention is validated by analyzing and processing real radar scenarios. The detection area is mainly located near Pixian County, Chengdu, such as image 3 shown. The later verification is done on MATLAB-R2014a. The specific implementation steps are as follows:
[0047] S1. Static radar environment knowledge base modeling stage;
[0048] S11. Initialize radar parameters: radar coordinates [N30°45′19.31", E103°55′9.88"], radar maximum range R max =6Km, radar range resolution r=6m, radar angular resolution θ=1°, etc.;
[0049] S12. Establish a Cartesian coordinate system with the radar as the center, and the direction of the ordinate axis is due north;
[0050] S13. Establish each cell (x) with the radar distance resolution r=6m i ,y j ) has a side length of 6 m;
[0051] S14. Sort out the auxiliary knowledge attributes of the radar environment knowledge base, such as digital elevation values, landform coverage types, empirical amplitude distribution models, and...
