| 摘 要： | 在毫米波照射下,目标回波可模型化为多个散射中心回波的合成;宽带线性调频连续波(LFMCW)工作体制可以获得目标多散射中心在雷达径向距离轴上的投影分布,即高距离分辨率目标距离像(high range resolution range profile);综合利用距离像所提供的目标多散射中心空间分布和截面积信息,可以改善信号检测和跟踪性能,并完成目标识别。

| Abstract: | When illuminated by the millimeter wave, targets can be described in terms of returnsfrom scattering centers. When wideband LFMCW waveform is used, it is easy to obtain the high resolution range profiles (HRRP) which shows a spacial distribution of scattering centers. The detection or tracking performance can be enhanced by means of the spacial distribution and relative strengths information of HRRP and the target can be identified. |
