Algorithm of Passive Acoustic Locator Data Processing for Flying Vehicle Detection and Tracking

This paper deals with the development of the special algorithm of digital signal processing, which allows to detect flying vehicles and define their coordinates and radial velocity. The coordinates are used for trajectory tracking. The velocity is useful to distinguish maneuvering objects. Detection of an object is based on calculation of ambiguity function. It is proposed to do it by spectral method instead of classical integration. This is one of advantages of the developed algorithm.
