| Abstract: | The finite multicycle detector is presented for LPI phase-coded signals.This detector is easy to implement,and takes advantage of the main cyclic-frequency features of signals to improve the performance.The expressions of the finite multicycle detector in white noise with variable and constant power are given in this paper.The deflection of the finite multicycle detector is analyzed and is compared with other detectors.The performance of the finite multicycle detector has been evaluated by computer simulations. |

| Keywords: | finite multicycle detector phase-coded signal low probability of intercept detection |
