Analysis and correction methed of low-elevation lobe split in UHF band passive radar
摘要
Abstract
Aiming at the problem of lobe split affecting the elevation detection airspace coverage when low-band passive radar performs long-range early-warning detection in the case of low elevation,this paper first analyzes the forming causes and influencing factors of lobe split,then based on the idea of array flow pattern fit-ting,proposes a method of solving the correction transformation matrix using least square method,and finally,conducts simulation to analyze the effect of angle quantization interval and angle transform interval on the correc-tion error,verifying the validity of the correction method.This provides a reference for improving the perfor-mance of passive radar based on digital broadcast television signals.关键词
