A correction method of amplitude-phase imbalance for digital receiver of a monopulse radar is presented, and its application in a real radar system is introduced.
Finally, the validity of digital correction is verified by simulation and practical measurement of a UWB quadrature demodulation receiver.
最后，对某超宽带正交解调接收机的实际测量结果的数字校正，验证了这种方法的有效性。

The effect of amplitude and phase error on the performance of receiver is discussed in this paper, and a method of digital correction based on FIR filter is proposed.
