The segment correlation-video integration method using square-law detector for binary phase-coded signals detection under carrier Doppler, in which the signal is successively IF integrated, square-law detected and video integrated, are analyzed. The processing loss formula has been derived. Using the maximum processing loss minimum criterion, the optimum IF integration time is analyzed in two different cases, one is specifying the whole integration time and the other is specifying the detection performance. The results can be used for receiver design of spread spectrum system and navigation system.
