Recently, a new type of sabotage and terrorist actions has appeared with the use of rocket fire at critically important objects. The use of low-flying high-speed small-sized objects – anti-tank guided missiles (ATGMs) – allows the enemy to hit these objects while outside the perimeter of the protected area. The fight against ATGMs can be ensured through the use of information systems for automatic detection, recognition and classification of objects for various purposes.

Goal of the work is to synthesize an algorithm for distinguishing the type of an object from its acoustic signal based on the experimentally obtained emission spectra of acoustic signals of low-flying high-speed small-sized objects, using the theory of detection, estimation and modulation.

The acoustic signals of low-flying high-speed small-sized objects of various types have been experimentally investigated. The spectra of these signals were obtained and, on their basis, the synthesis of an algorithm for distinguishing (recognizing) types of objects was carried out in the presence of uncertainty about the variant of the technical appearance of the object. It has been established that in order to correctly determine the hypothesis about the type of ATGM, the error in measuring the levels of acoustic radiation should be no more than 25% of the root-mean-square deviation of the reference values of the relative levels of the integral power..
