摘　　要：对比宽、窄带雷达系统对目标距离和角度的测量精度,建立目标回波模型,并分析宽、窄带雷达系统测量的理论精度;通过计算机仿真,考察了信噪比、目标包含的强散射点个数以及强散射点幅度的相对取值对宽、窄带雷达系统测量精度的影响。由理论分析和计算机仿真结果可知,宽带雷达系统对同一目标距离和角度的测量精度高于窄带雷达系统。Measurement precision of wideband and narrowband radar for target range and angle are comparatively studied. Echo model of target is set up, and the precision in theory of wideband and narrowband radar is analyzed. The effects of signal noise ratio, scattering points of target and relative amplitude of scattering points on precision are simulated by computer. From theoretical analysis and computer simulation, results show that the precision of wideband radar measurement for the same target is higher than narrowband.
