Linear frequency modulated continuous wave (LFMCW) is a typical common waveform and it shows good performance. But, the zero-difference receiver seriously affects the performance of the radar. Intermediate Frequency(IF) receiver is a development direction of modern high-performance radar. According to the characteristics of the LFMCW signal, the signal is mixed with the delayed signal to generate a constant single frequency signal. The simulation results show that the design scheme of the IF receiver based on the time delayer is feasible, and the IF signal can be shifted to the baseband by downsampling. The IF receiver based on time delayer can replace the current structure.
