Simulation device for angularly to radar target multi -

摘要

The subject of the invention is a device intended for testing the angular detection function of a multi-target radar. This device includes principally a reflector R1 in the shape of a semi-ellipsoid of revolution, the antenna A of the radar under test being arranged at one of the foci F2 of the ellipse, and at least two sources E1, E2, simulating two distinct targets, arranged in the vicinity of the other focus F1. The surface of the reflector R1 has grooves whose effect is a spatial phase-modulation of the reflected beam and, consequently, at least one lobe deflected by a specified angle with respect to the direction of reflection on a plane. The two sources E1, E2 are then arranged so that their deflected lobe 17, 19 reaches the axis aa of the ellipse at the latter's first focus F2. Application to self-guided missile testing. IMAGE
