Abstract
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 antenna array surface to be measured is achieved. According to the invention, a full-array-plane and full-power radar system can be tested, the influence of residual waves existing in the test environment on key technical index verification is avoided, the test environment can simulate and restore the actual working scene of the radar to be tested, and the credibility of the test result is further improved.
Description
technical field [0001] The present application relates to the technical field of radar testing, in particular to a radar reliability testing system. Background technique [0002] With the development of radar test technology, radar reliability test system has appeared. In the development, finalization and batch production stages of radar, the reliability level of radar can be tested by carrying out reliability test, growth test, identification test and acceptance test, etc., and ensure that the radar has a high level of reliability. During the reliability test of the radar, testing the key technical indicators of the radar is an important content of the radar reliability test. Among them, the key technical indicators can be the technical indicators of the radar system in the full array and full power working state, such as the transmitted signal spectrum, power-aperture product, continuous transmission time, etc. [0003] However, during the implementation process, the inv...
