Design of Receiver Performance Online Monitoring System in Radar BIT

In view of the limited ability of conventional BIT monitoring, the performance of radar receivers cannot be monitored without obvious symptoms of failure. To solve the problem, a receiver performance monitoring system in radar BIT is designed. The system consists of embedded computer, virtual instrument module and receiver performance parameter monitoring module, which can complete on-line monitoring of receiver sensitivity, noise coefficient, improvement factor, amplitude and phase consistency and other performance indicators. The system has been applied in a radar receiver performance monitoring system, which effectively solves the problem that the radar BIT state monitoring capability is limited, and the effect is good.
