相控阵雷达搜索方式下波位编排与优化

分析不同波位编排方式对相控阵雷达能量需求与搜索性能的影响,给出了搜索方式下较为优化的波位编排方式。然后在分析相控阵雷达波束展宽效应的基础上,提出了非均匀划分扫描空域并对波束展宽效应进行补偿的方法,对波位编排方式进一步优化。最后利用该方法仿真分析了波束宽度与天线增益的变化,结果表明可有效补偿波束展宽效应带来的影响。

Beam Position Arrangement and Optimization for Phased Array Radar in Search Mode

Different beam position arrangements affect the energy requirements and search performance of phased array radars.This paper provides an optimal beam position arrangement.Then,on basis of analysis of the beam width extension of a phased-array radar,a new method that divides scan space in an uneven manner and compensates for beam width extension effect is proposed for further optimization of beam position arrangement.Finally,the method is used to simulate changes in beam width and antenna gain and the results show that the optimization method is effective to compensate for disadvantages of beam width extension for phased array radars.
