星载雷达对电源的体积、重量和可靠性有着严格要求,并且环境条件苛刻,针对上述环境特点和边界条件,提出了星载天线电源结构设计思路,并着重讨论了抗力学环境、抗热环境、抗辐照等环境适应性设计关键问题。设计结果和试验证明,电源具有良好的工作稳定性和可靠性,表明了环境适应性设计合理有效,对星载雷达电源的结构设计具有参考意义。

Space-borne radar makes strict demands on its power supply′s volume, weight, stability and environmental worthiness. According to the work environment characteristics and boundary conditions of the power supply for a space-borne radar, the overall structure design method of the power supply is proposed. The key issues of the environmental adaptability designs, including mechanics-resistance design, thermal-resistance design and anti-irradiation analysis are focused. The result and the final test have proved that the power supply has good work stability and reliability, and the design of the power supply is reasonable and effective.
