对一种对空监视情报雷达采用宽带技术提高目标监视、跟踪性能进行了分析和仿真,研究了多径传播引起的分裂波瓣,其凹口以及峰值所在角度,并且对多频点的雷达威力进行了合成分析.结果表明,适当增加雷达系统带宽,可以大大减少由于多路径传播造成的波瓣分裂影响,进而比较显著地提高情报雷达的目标监视和跟踪性能.其结果对于要求具有自动检测和跟踪的对空情报雷达特别重要.

[Abstract]
Analysis of air surveillance intelligence radar with wide-band technique for improving surveillance and tracking performance is presented in this paper. Position of the notch and peak of split-beam due to the effect of multipath propagation are calculated. The comprehensive analysis of the coverage of radar at different frequency points is also given in this paper. It is shown that the effect of multipath propagation can be greatly reduced through broadband technique. Thus,the surveillance and tracking perf...
