ABSTRACT

In this paper the algorithm of signal detection by means passive acoustics and digital data processing is proposed. This algorithm is original and contains the processing of signals, which are received from several acoustical aerials. For signal detection the calculation of wide-band ambiguity function together with its projection on time axis are used. All the calculations are executed using the real signals. As the result the location of the aircraft on the Cartesian coordinate plane is observed. The suggested algorithm is also proposed to use for measuring of aircraft noise with the aim of environmental protection.
