等高线投影分析法及其在电子侦察卫星系统设计中的应用

Analytical Method of Contour Projection and its Application in System Design of Electronic Reconnaissance Satellite

基于覆盖分析和链路计算的基本方法,将卫星的轨道高度、空间链路、侦察天线和接收处理能力等因素综合,提出了一种通用的等高线投影图形显示方法。通过应用举例指出该方法可在不同轨道高度、不同天线方向图形状和指向,以及不同处理能力等条件下分析卫星轨道和侦察载荷等参数的设计是否满足使用要求,从而为电子侦察卫星系统的设计论证提供有力支撑。

Based on the basic methods of coverage analysis and link computation, in consideration of the satellite orbit height, space link, reconnaissance antenna, receiving and processing capacity and other factors, a general method of graphic display through contour projection is proposed. Application indicates that the method can be used in different conditions such as different orbit height, antenna pattern shape and point, and different pro- cessing ability. It can analyse whether the design parameters of orbit and reconnaissance payload satisfy the re- quirements for use or not, thus providing useful support for the system design and demonstration of electronic re- connaissance satellite.
