介绍了一个由均匀线接收阵和米波雷达组成的外场实验系统,用于进行米波雷达的方位角超分辨实验。用采集的实验数据对几种常用的超分辨算法进行了实验,结果表明,FBLP算法和ESPAIT算法可清晰分辨出角间隔为0.2~0.3波束宽度的两架飞机。
An outfield experiment system consisting of uniform linear receiver array and m-wave radar is introduced for azimuthal super-resolution experiment of m-wave radar. Experiments on several commonly used super-resolution algorithms are carried out using the collected experimental data. The results show that the FBLP algorithm and the ESPAIT algorithm can clearly distinguish two aircraft with angular spacing of 0.2-0.3.
