Trend Prediction and Analysis of Key Parameters of Transmit Power Supply Based on Accelerated Degradation Test

摘要:

雷达发射电源作为雷达最重要的组成部件，其稳定性与质量高低直接影响整个雷达设备运行的可靠性与性能指标的实现，同时电源需要连续运行，还要承受高、低温及高湿、冲击等考验，运行中不允许检修或者只能进行简单的维护，因此探究发射电源的性能退化规律，并对其进行有效的预测十分有必要；通过详细分析发射电源失效机理，并开展发射电源性能退化试验，并对各试验数据进行有效的分析，探究电源各监测参数相关关系，建立电源各关键参数退化模型，从而实现对发射电源的故障预测或者关键参数的趋势预测。

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.
