摘　　要：基于提出一体化卫星理念与运行机制,给出一套一体化星星载射频系统综合方案的目的。采用对比星载雷达、通信、电子侦察系统的方法,确定一体化星的基本指标,一体化星的运行机制与可重构载荷原理。采用对比通信、雷达、电子侦察各自的接收机和发射机架构的方法,确定综合系统接收机和发射机的设计原则与架构,确定相控阵综合设计的原则和基于相控阵的综合系统的架构。得出星载通信-雷达-电子侦察载荷系统射频部分一体化初步综合方案。该方案基于相控阵,可同时实现多种功能。A concept and operation mechanism of satellite integration were proposed, and a set of integrated program of spaceborne RF system of integrated satellite was given. The basic indicators of integrated satellite is determined, by contrasting spaceborne radar, communications , electronic reconnaissance systems. And the operating mechanism of integrated satellite and reconfigurable payload principle are determined. The design principles and architecture of the receiver and transmitter of integrated system are determined, by contrasting architecture of the receivers and transmitters of communication, radar, electronic reconnaissance systems. The principle of phased array integrated design and the architecture of integrated system based on phased array are determined, according to the respective characteristics of communication, radar, electronic reconnaissance systems. Finally, the integrated program of spaceborne communications-radar-electronic reconnaissance payload system integration was gotten. The program is based on phased array, which can achieve multi-function.
