This paper considers the problem of moving source localization by introducing an additional Doppler frequency shift (DFS) measurement into the previous location system using time differences of arrival (TDOAs) and frequency differences of arrival (FDOAs). Because of the separation of associated data channels and the difference in the estimation techniques, the DFS is independent of TDOA and FDOA measurements...
Radar emitter's position can be estimated by dual satellites location system utilizing DTO (differential time offset) and DFO (differential frequency offset). Signal model received by dual satellites is given and the influence to signal accumulation by relative motion is analyzed in this paper. Then the upper limit of accumulated pulses' number is given. The Cramer-Rao lower bounds (CRLB) of DTO and...
By measuring the DTO (differential time offset) and DFO (differential frequency offset) from two satellites, the emitter's position can be estimated by dual LEO-satellites location system. But it is difficult for broadband frequency-hopping pulse signal, because the pulses of different frequency points can't be accumulated due to doppler varying with carrier frequency. On the other hand, the parameter...
