不确定区域天线扫描目标捕获方法
Target Capturing by Antenna Scanning in Uncertain Areas
摘要
Abstract
To resolve the contradiction between the requirement for fast antenna scanning and relatively un-satisfactory dynamic performance of mechanical structure in space telemetry tracking and command ( TT&C) stations,this paper designs a track algorithm of circular scanning and spiral scanning based on the sinusoidal variation of antenna azimuth and elevation angle velocity, proposes the principle of selecting scanning modes according to the motion characteristics of targets,and illustrates the calculation methods of scanning parameters with examples. The calculation and simulation results show that the methods men-tioned are able to keep antenna acceleration within its design indexes and target acquisition probability con-trolable. The calculation methods of scanning parameters as mentioned have been partly applied in China's Lunar Exploration Program.关键词
