Simulation And Analyse Of Passive Locating And Tracking LEO By HEO

To the HEO-to-LEO passive locating problem, this paper analyses and realizes two passive locating methods: the method using bearing-only measurement and the method using bearing and frequency measurements. And then it realizes the passive locating software to the problem. After this work, the paper analyses some factors, such as the precision of bearings measurement and the precision of frequency measurement, which can influence the performance of the two methods. And then it compares the performance of the two methods.Computer simulation indicated that it is possible to track LEO by HEO using the two methods when the precision of measurement can be guaranteed. In the two situations, the precision of bearings measurement and the precision of frequency measurement should be guaranteed to improve the performance of the two methods. In the same precision of measurement, the performance of the method using bearing and frequency measurements is better than the method using bearing-only measurement.
