摘要
文中对双极化雷达高分辨距离像进行不同收发极化态非相干积累、邻近方位角数据压缩和背景杂波电平抑制,获得数据量少、信杂比高的目标特征像,利用以上方法建立五种地面目标特征像数据库,然后对此五类目标进行分类,可以获得较高的识别率。
The dual polarization radar high-resolution range profiles are processed as follows: different receive/send state noncoherent integration,near azimuth data compression and noise level inhibition. After the processing, we obtain less and high signal-noise rateo target feature profiles. Using the above methods, we set up target feature data library of five ground targets. High classification performance can be obtained using the feature library to classify the five ground targets.
