摘要
将宽带雷达的高分辨目标检测视为随机幅度随机相位非相参脉冲串检测问题,研究了高斯白噪声中高分辨目标的检测性能,并与窄带点目标的检测性能进行比较。分析表明,宽带雷达在信噪比较高时检测概率也较高,优于窄带雷达,但是宽带雷达的带宽不能过大,将目标分辨为5-10个距离单元为宜。
Taking high resolution target detection of wideband radar as the detection of noncoherent pulse train with stochastic amplitude and stochastic phase,this paper studies the detection performance of high resolution target in Gauss white noise,and compares it with the detection performance of narrowband point target.The analysis results show that the detection probability of wideband radar is high and superior to that of narrowband radar when the signal to noise ratio（SNR）is higher,but the bandwidth of wideband radar can not be too wide,and it is appropriate for the wideband radar to resolve the target into 5-10range cells.
