摘要
雷达测定目标的方向是利用天线波束的扫描来实现的。在对传统机械扫描、电扫描方法简要分析的基础上,根据软件机械的设计理念[1],提出了两种雷达波束扫描功能的软件实现方法———软件移相和空间谱估计,并给出了软件实现框图。软件测向仿真结果表明:提出的软件实现方法可以很好地实现雷达波束的扫描功能。
The direction of Radar Target is got by antenna beam scanning. After analyzing the traditional mechanic scanning and electronic scanning methods briefly, two software realization methods, that is softwarephase-shifting and spatial spectral estimation are proposed according to the design philosophy of the software machinery . The software realization chart is also presented. Simulation results show the proposed software realization methods can realize the function of radar beam scanning well.
