DEVICE FOR RECOGNITION OF AIR AND SPACE OBJECTS IN TWO-BAND RADAR COMPLEXES WITH ACTIVE PHASED ANTENNA ARRAYS (AFAR)

摘要

FIELD: radar ranging.SUBSTANCE: invention relates to radiolocation and can be used to recognize classes of aerospace objects (ASO) in dual-band radar complexes with two-dimensional electronic scanning. This result is achieved due to the fact that, in a device comprising a radar information processing unit, a vertical speed component calculator, a road speed calculator, a first-level classifier, classifier of the second level, calculator of the recognition frequency, averaging unit of the frequency characteristic, a calculator of the effective scattering area, averaging unit of the effective scattering area, and also a parametric classifier, In addition, a device for selecting air objects, a device for selecting operating frequencies and a longitudinal size calculator, connected in a certain way. In addition, the processing unit is made with the additional capability of generalized (from two modules) secondary processing of radar information and calculation of the route priority based on data on the results of state recognition of the air facility, its range and flight speed.EFFECT: achieved technical result of the invention is improved tactical and technical characteristics and reduced time of recognition, increased boundaries of information about the recognized class of the target, increased alphabet of recognizable classes of ASO at a sufficiently high level of probability and reliability of correct recognition of the target class.1 cl, 1 dwg, 1 tbl
