摘要
星载天线是卫星系统的重要载荷,在远距离微波遥感、深空探测、军事侦查以及通信等领域起着决定性作用。随着天线频率和增益需求的不断提高,大口径、高精度成为星载天线主要发展方向。传统被动方法难以保证反射器在轨形面精度,而主动控制技术正成为解决这一问题的重要选择。介绍了天线反射器形面主动控制技术相关研究工作的进展,内容涉及形面主动控制方案、作动器技术、形面主动控制方法、高精度形面测量以及形面主动控制实验系统,分析总结了星载天线形面主动控制相关的关键技术,并对其发展进行了展望。
The space-borne antenna is an important payload of the satellite system,and plays a decisive function in the field of microwave remote sensing,deep space exploration,military reconnaissance,and military communication.Large-aperture and high-precision have become the main development directions of space-borne antennas with the increasing demands for antenna frequency and gain.Traditional passive methods are difficult to guarantee the shape precision of the reflector on orbit,and the active shape control technology is becoming an important selection to solve the problem.The research progress of active shape control technology for antenna reflectors is introduced.The contents include active shape control schemes,actuator technologies,active shape control methods,high-precision deformation measurement ways,and experimental systems of active shape control.Key technologies of active shape control for space-borne antennas are analyzed and summarized,and the development is prospected.
