摘　　要：分析了连续波雷达接收机中正交通道幅相不平衡产生的镜像信号对测量的影响,并根据连续波雷达测速、测距原理提出了一种新的幅相不平衡校正方法,该方法基于数学中的正交化思想,提取的幅相不平衡校正参数精度较高,仿真结果也表明了这一点。The influence of image signal to the measurement is analyzed, which is caused by amplitude and phase imbalance of quadrature channels in multiple frequency CW radar＇s receiver,and a new correction method is proposed according to the principles of range and velocity measuring of the radar. The method is based on the theory of quadrature in maths,and the accuracy or＂ the correction parameters extracted is high. The simulation results prove it.
