Claim 6:
7. An apparatus, the apparatus comprising processing circuitry coupled to storage, the processing circuitry configured to:
operate a gimbal setup attached to a mounting arm disposed inside an anechoic chamber and a radar to modify an azimuth angle and an elevation angle of the radar, wherein the mounting arm removably positions the radar that is under test within the anechoic chamber;
cause the radar to transmit one or more signals towards one or more reflectors situated in a field of view of the radar through an aperture formed through a sidewall of the anechoic chamber, wherein the one or more reflectors are situated outside the anechoic chamber and the sidewall is shaped to allow one or more signals to travel from an area inside the anechoic chamber to an area outside of the anechoic chamber via the aperture;
using an anechoic material to reduce diffraction by an edge of the aperture, wherein the anechoic material covers an edge of the aperture;
receive reflected signals from the one or more reflectors at the radar, wherein the reflected signals pass through the aperture before reaching the radar;
measure signal energy of at least one of the reflected signals; and
generate an output indicating an operational status of the radar.
