FIELD: physics.
SUBSTANCE: invention relates to tests of vehicles on susceptibility to electromagnetic field. In the anechoic chamber, the geometric center location points and the hypothetically established vehicle calibration are set and calibrating the power of the emitted EMF. Installation of tested vehicle is carried out with reference to these points. Values of large and small semi-axes of geometric ellipse inscribed in outer contour of vehicle are calculated. Values of the large and small semi-axes of the geometric ellipse, the contour of which passes through the calibration point of the electromagnetic field, and the EMF level calibration loop, are calculated. Azimuth angle of vehicle positioning in relation to radiating antenna is set as specified by test plan of testing, mode of onboard electric equipment of PBX is set and required EMF parameters are set. In the process of testing, the emitting antenna and the vehicle are positioned so that the longitudinal geometrical axis of the main lobe of the antenna beam pattern passes through the geometrical center location point tested vehicle, and the distance between the antenna and the geometric circuit of the EMF level calibration remained invariable at each of the azimuthal positioning angles of the vehicle relative to the emitting antenna.
EFFECT: invention provides verification of onboard electric equipment of vehicle for noise immunity at any angles of azimuthal positioning of vehicle relative to antenna emitting an electromagnetic field.
