“…These methods need the deployment of large antenna arrays which is very expensive and requires an estimate of the ionospheric profile along the propagation path. When considering time-domain methods, we estimated that geolocation of HF Tx's is possible with an error of about 25 km without the knowledge of the ionospheric profile along the propagation paths [5]. Furthermore, by increasing the number of receivers, the geolocation accuracy is improved significantly using time domain methods [6].…”

In the context of passive geolocation of High Frequency (HF) transmitters using the Time Difference of Arrival (TDoA) method, the transmitted signal and the propagation channel is unknown. This paper explains the principle of a method termed as "cross-channel sounding" along with its concepts. This method is used to evaluate the propagation duration differences of an unknown signal received by multiple synchronized distributed receivers. The mathematical description for cross-channel sounding is detailed, emphasizing the importance of the nature of the transmitted signal in the estimation of the propagation duration differences. An operational country wide TDoA receiver network capable of capturing HF signals is presented. HF broadcast signals are captured from different transmitters around Europe. Experimental data are used to analyze the different propagation modes from cross-channel sounding and assess the TDoA estimation complexity in the case of multipath channels.

“…In our previous study of ToA geolocation [6], the Tx location was obtained without the knowledge of reflection height and the minimum number of 3 required Rx's. The geolocation error was in the range of about 50-100 km depending on whether the transmitter was very close or far away from the Rx's.…”
