摘　　要：随着大口径、高频段反射面天线的应用,由重力、热和风等因素引起的主反射面变形会导致天线性能明显下降。如果合理的天线设计还不能满足性能要求,需采用补偿方法来提升天线性能。文中综合介绍了常见的两种补偿方法:机械补偿方法和电子补偿方法。通过对各种方法的总结来展望未来大型高精度天线补偿技术的发展方向。With the application of large-aperture high frequency reflector antenna, detormation of main retlec- tor caused by gravity, heat, wind and other loads will greatly decrease antenna performance. When appropri- ate antenna design can not meet the performance requirements, compensation methods are used to improve the antenna performance. In this paper, an overview of two common compensation methods, mechanical compen- sation and electronic compensation, are introduced. By summarizing various compensation methods, the future development direction of compensation technology for large high-precision antenna is discussed.
