Radar reliability test system

The invention relates to a radar reliability test system. The radar reliability test system comprises a middle-far field wave absorbing channel; a three-in-one comprehensive test box, wherein the three-in-one comprehensive test box comprises a climate box for accommodating a radar to be tested, the climate box comprises a first inner wall facing the middle-far field wave absorbing channel, and a wave-transparent window is formed in the first inner wall; a wave-transparent plate which covers the wave-transparent window to seal the climate box; an in-box wave absorbing device which is laid on the absorbing inner wall, wherein the absorbing inner wall is the inner wall for reflecting electromagnetic waves in the climate box when the electromagnetic waves emitted by the radar to be detected are transmitted to the middle-far field wave absorbing channel. According to the invention, reflected waves can be eliminated; directional and efficient absorption of electromagnetic wave energy radiated by a high-power radar
