Retrieving aircraft motion parameters, using acoustic passive radar

This paper presents the method and a special approach to signal processing in acoustic passive radar for retrieving aircraft motion parameters. The algorithm of aircraft position determination based on its acoustic noise measurement is developed. This algorithm makes processing of multiple input signals, which are received from several acoustic aerials with definite number of microphones in each of them. The original algorithm of calculation of wide-band ambiguity function together with its projection on time axis is used. Also, the method of obtaining aircraft velocity vector is proposed.
