TDOA Location With High PRF Signals Based on Three Satellites

The TDOA(time difference of arrival) ambiguity may occur in TDOA location with high PRF(pulse repetition frequency). The large numbers of ambiguous TDOAs produced by pulse pairing, not only reduce the speed of processing, but also interfere the extraction of TDOA produced by other signals and pulse deinterleaving. A new method is presented to solve the problems of signal processing and location effectively.
