1. A system for testing a radar under test comprising:
an antenna array with a plurality of antenna elements;
a plurality of transceivers correspondingly connected to the plurality of antenna elements; and
a processor; and
wherein the processor is configured to control the system to perform reception testing of the radar under test by (i) controlling the gain and phase of the plurality of transceivers to generate a first radiation pattern to simulate a radar reflection on the radar under test, (ii) controlling transmission, via the antenna array, of the first radiation pattern to the radar under test, wherein the first radiation pattern corresponds to a digital image and is in the form of a first complex radio frequency image, (iii) receiving, via the antenna array, a second radiation pattern from the radar under test, and (iv) analyzing the second radiation pattern with respect to a known test pattern of the digital image.
