摘要
Abstract
An improved relative measurement method is proposed for the RCS inversion problem in target tracking of phased array precision tracking radar.This method considers the influence of factors such as the azi-muth,elevation,tracking pulse width,pulse number and working frequency of the standard metal ball relative to radar normal in the process of using standard metal ball for K-factor calibration.And then,the calibrated K-factor is used to perform real-time RCS calculation on the target to be measured under different azimuths,elevations and tracking waveforms.The feasibility and effectiveness of the proposed method are verified by the measured data.This method is simple,practical and highly accurate with universality and engineering application value.关键词
