Radar anti-jamming application of solid-state noise source

Jamming reconnaissance receiver (JRR) is an important anti-jamming equipment of radar. In this paper, we propose a compensation method based on solid-state noise source to against the performance degradation of JRR caused by long-term aging, which can compensate all channels simultaneous and accomplish by JRR itself. First, presented the structure of JRR, analyzed the principle and structure of solid-state noise source. To reduce the influence of ambient temperature on compensation performance, then we given and compared two solutions: constant temperature mode and table lookup mode. At last, advanced a method using attenuator to simulate the influence of long-term aging, and carried on a contrast test. The test results show that, the aging process has no effect on the performance of JRR after the compensation based on solid-state noise source, the long-term stability of JRR has been improved greatly.
