毫米波辐射计对金属目标的探测

针对金属目标的探测问题,依据金属的毫米波辐射特性,提出一种基于毫米波辐射计成像的金属目标探测方法。该方法首先利用毫米波辐射计扫描目标并成像,再用区域标记算法标记成像图像,通过分析标记区域的面积排除干扰信息,最后检测出金属目标。实验表明,该方法能够从各种背景中有效检测出金属目标,为下一步目标的识别、跟踪与定位提供了依据。

Research on Metal Target Detection by Millimeter-wave Radiometer

Aimed at the problem ofmetal target detection, a metal target detection method based on millimeter-wave radiometer imaging is proposed, according to the millimeter-wave radiometric characteristics of metal. Firstly, the method utilizesmillimeter-wave radiometer to scan target and image. Secondly, the image is labeled with region labeling algorithm. Thirdly, the fake target information is excluded through analyzing the area of labeled regions, and the metal target is then detected . Experimental results show that the method can detectmetal target effectively from various background, therefore, it provides a base for later target recognition, tracking and location.
