Trend Prediction and Analysis of Key Parameters of Transmit Power Supply Based on Accelerated Degradation Test
Abstract：Transmit power supply of radar, working as the most important component of radar system, the stability and quality of which directly affects the reliability of operation and the realization of performance indicators. Also, the power supply operates continuously, and withstands extreme temperature, high humidity and impact force. No overhaul is allowed during its operation except simple maintenance. Therefore, it is necessary to explore performance degradation rules of transmit power supply and make effective prediction on it. The failure mechanism of transmit power supply was analyzed in detail, and the performance degradation experiment was carried out. The correlation of the monitoring parameters was explored, and the degradation model of the key parameters was established by effectively analyzing the experimental data. Consequently, the fault prediction of transmit power supply or the trend prediction of key parameters can be achieved.
