摘要
某新型制导雷达在S曲线测试时发现,在波束展宽状态下曲线异常,针对此问题,进行了分析研究,确认由于天线波束展宽方法引起。对天线波束展宽方法进行了研究,进行了仿真和实际测试,试验表明采取外缘单元"0、π随机配相法"进行波束展宽满足任务要求,问题得到解决。
In S curve testing, new guidance radar is found to be unusual in condition of beam broadening. After the analysis, we trust this issue is caused by beam broadening method. So the method of antenna beam broadening is studied, simulated and tested. The experiment result shows that“0、л”random phase method is satisfied with the mission requirement and the problem is settled.
