| Abstract: | CDMA mobile communication system is a synchronous one. Because oi high PN chip rate of the system’s frequency spread code, it has better performance when it is used for passive detection. The scneme in which the passive detection is conducted by the pilot signal was put forward based on analyzing the feature of CDMA mobile communication signal. The expression of the signal was de?duced, and the detection performance ol it was simulated. The result shows that the pilot signal has good detection performance both in distance and velocity, can be used for passive detection. |
