RCS测量误差与相位信息的定量关系

THE RELATIONSHIP BETWEEN THE ERROR OF RCS MEASUREMENTS AND THE PHASE OF TARGETS RELATED TO THE BACKGROUND

目标散射场的特征信息是十分丰富的,充分利用相位信息可以大大提高雷达截面(RCS)的测量精度。本文首次分析了 RCS 测量误差与相位ψ,相位误差△ψ的定量关系,给出了 RCS测量误差分布曲线,可供工程应用参考。根据分析得出了最佳测试条件。

The scattering field of targets has many character parameters.Fully utilizingthe phase of targets related to the background can greatly improve the precision ofRCS measurements.This paper first gives the relationship betmeen the error of RCSmeasurements and the phase of targets relateel to the background,(?),and the error of phasemeasurements,Δ(?).Distribution curves of the error of RCS measurements are given as areference in engineering.The optimum conditions of RCS measeurements are obtained based onthe analysis.
