This paper introduces the construction of the SAW matched filter for chip/carrier asynchronous S-S signal. The validity of the matched filter for detection of the correlation signal has verified by simulation and experiment. 18 dB D/U ratio has been obtained in the correlation output of the S-S synchronous signal demodulation circuit involving the asynchronous type SAW matched filter of the carrier frequency 375 MHz and the spread signal band width 140.395112 MHz.
