Study of location based on T-R and T/R-R mode in Bistatic Radar

In this paper we analyze some methods for the location in bistatic radar and present two novel methods for location in the shipborne passive synthetic impulse and aperture radar (SIAR) that is a ground-wave over-the-horizontal-radar (GW-OTHR). The novel methods are based on the analysis of overwhelming error we encountered in practice. Since the accuracy of location in bistatic radar is sensitive to the position of target, we explore redundant information to interpolate higher accuracy position information when radar works in T/R-R mode. The approaches ameliorate the performance of detection when limited information about target can be acquired. Moreover, analysis and simulation results which show the efficiencies of the two new approaches are presented
