Analog signal processing based radar systems enable reduction in total system power consumption, over conventional digital signal processing based radar systems. In this paper, detection performance degradation of a previously proposed system, based on analog cross-correlation, due to time synchronization is addressed and analog auto-correlation based radar architecture is proposed. By adopting the digital radio frequency memory technique, accurate and tunable delays for auto-correlation process are realized. The probability of detection performance degradation of the previously proposed system, due to mismatch, is evaluated by simulations while varying signal to noise ratios and mismatches at the matched filter.
