Position accuracy improvement based on bistatic OTH radar

Since the narrow working band, the position accuracy of coast/ship bistatic high frequency surface wave radar(HFSWR) is low, and it is related with the location of target. In this paper, the application of triangle barycenter method (TBC) and three-points weighted mean method (TWM) are presented based on T/R-R working mode. The methods improve the position accuracy of bistatic over-the-horizon (OTH)radar.The results of simulation verify the efficiency of the methods.
