FIELD: measurements of radio-location chars of equipment object with reproduction of their radiolocation images.
SUBSTANCE: method is based on registration of amplitude diagram of reverse dissipation of object together with mobile supporting reflector S(φ), in form of a function of current observation angle φ within interval of angles Δφ≪1 rad and Fourier transformation S(φ) and computation of square modulus thereof for each fixed angle φ0, while registered at interval of observation angles Δφ are: reverse dissipation diagram of object without supporting reflector S0(φ) and reverse dissipation diagram of object together with mobile supporting reflector S1(φ), mounted on a platform of supporting-rotary device of measuring radiolocation complex at a distance from rotation axis exceeding half the maximal linear dimension of object in direction, perpendicular to pointing direction of object, difference reverse dissipation diagram is built based on them and by means of computation of Fourier transformation ΔS(φ) and square modulus of that transformation, radiolocation image of object is reproduced.
EFFECT: increased dimensions of working zone of measuring radiolocation complexes.
