| 1. | ( 2 ) . according to the system indices and requirements together with the technology characteristic , it researches the capture possibility of apt capturing system . then it introduces the common scan methods , such as raster , spiral , raster spiral , rose and lissajo . ( 3 ) . it makes a detailed simulation analysis of the raster and spiral scan , analyze the connection between capture probability , capture time , system index at different capture resolution angle , capture range , vibration angle extent and terminal location distributing mean square deviation
其中对几个关键部分进行了详细分析:计算了目标角反射器的激光雷达散射截面( lrcs )值,研究了qd与ccd对目标位置角度的计算方法和空间分辨率; ( 2 )根据系统指标和要求并结合现有国内技术特点研究了apt捕获系统扫描的捕获概率问题,然后分析了几种常见的扫描方式:矩形( raster )扫描、螺旋( spiral )扫描,矩形螺旋( rasterspiral )扫描,玫瑰形( rose )扫描以及李萨如形( lissajo )扫描; ( 3 )对分行扫描和螺旋扫描进行了详细的仿真分析,分析了它们在不同捕获分辨角、捕获范围、振动角振幅和终端位置分布均方差时的捕获概率、捕获时间与系统常数之间的关系。 |
