| 摘 要： | 对基于宽带毫米波工作体制的雷达目标特征获取和识别方法进行了综合分析和探讨.表明:在毫米波照射下,雷达目标可模型化为由多个散射中心组成的扩展目标;只要发射信号有足够的带宽,就可以从回波信号中获得各散射中心的空间分布、类型等特征;仿真结果说明,这种方法对高频区复杂目标的识别是有效的.

| Abstract: | A method for feature extraction and target recognition by using wide-band
millimeter wave technology is presented. It is shown that radar targets can be described in
terms of multiple scattering centers at the operating frequency of millimeter wave. With a
modest bandwidth of the transmitted signals, features about spacial distribution, category
and polarization of scattering centers can be extracted from the received signals. The meth-
od is effective for high-frequency recognition of complex targets. |
