Abstract
A new IF module for linear frequency modulated continuous wave (LFMCW) radar is proposed in this paper, which is implemented with a low-cost and simple architecture and can be used for high sweep frequency. The scheme can improve system SNR and support implementation of a time-division switching antenna array (TDSAA). The performance of the scheme is analyzed and the experimental results are described in detail
