Abstract :
The I/Q channels are required to gain the amplitude and phase information of the radar echo signal. The adjustment of mismatch between the two channels is very important to radar system. Here introduces a practical method of the adjustment, and the mismatch information processing and the filter approximation result are included. The Matlab simulation result indicates that the approximation of the FIR filter has relatively high precision.
