超高频雷达基于河流回波的通道校准算法
Channel calibration algorithm for UHF Radar based on echo-signal of river
摘要
Abstract
A channel calibration algorithm based on the echo-signal of the river was proposed for the ultra high frequency (U HF) radar system .Since it was the radial velocity detected by the monostation radar ,the value from the front of radar was 0 m/s ,which reflected at the Bragg frequency of Doppler spectrum ,therefore ,this frequent point could be used to calibrate the channel .The method to cali-brate the UHF Radar system with the Bragg frequent point was researched .The field experimental re-sults show that the method can effectively improve the performance of spatial estimation algorithm and increase the accuracy of direction estimation .关键词
