| Abstract: | Considering the practical engineering problems of spaceborne TDOA and FDOA location for radar emitter on the surface of ground/sea,some key problems of coherent multi-pulse accumulation of radar pulse signal are studied.Firstly,the method of TDOA and FDOA measurement is analyzed.Secondly,the ambiguity condition of TDOA/FDOA is analyzed,and the method to solve the ambiguity is given.Finally,in order to solve the problem of estimating time-varying FDOA,the compensating strategy is provided. |
