摘要
该文将图像边缘检测技术应用到联合变换相关器(JTC)中,采用Sobel算子作为边缘检测算子,并应用VC++软件模拟仿真相关探测中物面图像的功率谱和相关峰。利用该方法获得了更加尖锐的相关峰,提高了目标的识别率,在探测低对比度目标时具有较好的效果。
In this paper, image edge detection is applied to joint transform correlator, and Sobel operator is used as the detect operator. Power spectrum and correlation peaks of object plane have been simulated by VC++ program in correlation detection. This method improved the ratio of target recognition, got much sharper correlation peaks than original image, and has better effect on detecting low contrast targets.
