固态有源相控阵雷达的幅相误差影响分析及其校准方法研究（上）

Analysis of the Effect and Study on the Calibration Method of the Amplitude and Phase Errors in a Solid-State Active Phased Array Radar(Part I)

主要讨论两个内容：（１）幅相误差对无线副瓣电平的影响及误差容量设计；（２）幅相误差校准原理及残差分析。提出了一种幅相校准的新方法，利用这种方法可以快速、准确、实时地对各环节的幅相误差进行监测和校准。这种方法具有较大的工程价值。

This paper concentrates on the following two issues:(1)analysis of the effect of the amplitude and phase errors on the antenna sidelobe level and the design of the error tolerance;(2)the study of the principle of the calibration of the amplitude and phase errors and the analysis on the calibration residue.A new calibration method is proposed in this paper and this method can provide fast,accurate and real-time calibration and adjustment of the amplitude and phase errors distributed among the overall stages.It will be of considerable engineering value.
