Emitter geolocation using a single moving receiving-station is explored. We propose algorithms for transponder-aided geolocation of an emitting station where the transmitted waveform is either known or unknown a priori. The emitter position is estimated directly (in a single-step) from the received signal samples. Numerical examples are provided to illustrate the performance. The results are compared with single-step algorithms for multiple-receivers geolocation system and with the Cramér–Rao lower bound.
