A Study of Radar Target Scattering Center Extracted and Its Recognition Method in Optical Region

首先回顾了在宽带体制下光学区雷达目标频域响应的特性 ,而后给出了矩阵束算法的原理 ,并应用该算法提取光学区雷达目标的散射中心 ,提出了所谓“基于散射中心极点和幅度的相关匹配目标识别方法” ,最后给出了五种飞机缩比模型宽带散射数据的实验结果。实验结果表明 ,该识别方法在白噪声条件下具有高识别率和强抗噪声能力。

In this paper, first, the characteristic of radar target frequency response in optical region is reviewed under the board band radar system. Then, the principle of matrix pencil algorithm is presented and radar target scattering centers are extracted based on it in optical region, a new target recognition method so-callsed “correlation match method by pole and magnitude” is proposed. Finally, the experiment result is given using board band scattering data of five aircraft models. The experiment result demonstrates that this recognition method has high recognition ratio and low sensitive to noise under white noise environment.
