摘　　要：基于目标的散射中心模型,对宽带雷达做了多种检测实验,并与窄带雷达进行了比较。仿真结果表明,在低信噪比时,窄带雷达的探测性能优于宽带雷达;而信噪比较高时,宽带雷达则具有更好的探测性能;宽带全匹配滤波器则具有理论上最优的检测性能。考虑到目标的先验信息不易获取,宽带雷达的探测性能将大大下降。Based on the backscattering target model, the detection performance of wideband radar is analyzed and compared with that of narrowband radar. Simulation results show that the detection performance of narrowband radar is superior to that of wideband radar under low signal-to-noise ratio （SNR） condition while under higher SNR, the wideband radar may achieve better performance and the detection performance of wideband all-matched filter is the best in theory. However, the prior information about the target is generally unavailable in practice and the detection performance of wideband radar will be decreased seriously.
