Tracking Optimization of FH Signal Based on Wiener Filtering

Article Preview

Abstract:

Comparing with the traditional fixed carrier frequency signal, using FH (Frequency-Hopped) signals improved the performance of anti-interference of the TT&C system when bring the low signal tracking accuracy. In order to solve this problem, this paper proposed a loop structure of using wiener filter, the filter coefficient was deduced. Simulation results show that the loop tracking precision was increased after the optimization, and the improvement has relations with the filter order n. When, the speed measuring precision reached 30cm/s which was increased about 3 times than did not use wiener filter.
