Detection of phase randomly distributed weak transient signal using chaos
摘要
In practical communication and radar system s, the phase of the received signal is random, the arrival time is unknown, the lasting time is limited and the SNR is often very low. In order to realize the detection of the signal, the method of using a group of nonlinear differential equations is presented. The theory of this chaos-based detection is analyzed. Computer simulation indicates that the shortest lasting time of the transient signal that can be detected out is 12 periods, the detection error of arrival time is less than 7/8 signal's period, the detection characteristics are got using Monte-Carlo simulation.
