基于中频采样数字正交技术的雷达接收机正交双通道处理新方法

IF Sampling Digital Quadrature Signals Processing Technique: A New Method of Quadrature Coherent Detector of Radar Receiver

针对模拟双通道处理中平衡不理想的问题 ,介绍了从中频信号的采样中获得正交双通道采样效果的数字正交技术 ,并对某 ASR-1 0 SS雷达接收机中的正交双通道处理器作了具体的分析 .

This paper introduces a new method of digital quadrature coherent detector by sampling IF output of the radar receiver in order to overcome the unsymmetrical problems of two branches of the analogue quadrature detector, and provides a reference model to make high performance quadrature coherent detectors.
