Abstract
FIELD: radiolocation, development and testing of radars. SUBSTANCE: proposed procedure consists in irradiation of target 1 with sought-for effective area of dispersion σs.f and target 2 with known effective area of dispersion σkn, from airborne radar station of interceptor in testing flight, in reception of reflected signals from targets 1 and 2 with the aid of same airborne radar station of interceptor, in determination of maximum detection range of target 1 and of target 2 in process of closing with targets 1 and 2 by airborne indicators. In this case trajectory of flight of interceptor and target 1 are kept invariable in process of closing. Flight is executed with energy potential of airborne radar of interceptor artificially diminished by value ΔL, computed by mathematical expression and sought-for effective area of dispersion σs.f is calculated by another mathematical expression. EFFECT: raised authenticity of determination of effective area of dispersion of targets in flight. 2 dwg
