In this paper, an optoelectronic hybrid processing system for cruise missile scene matching guidance based on convolute structure Joint-Transform-Correlator(JTC) was proposed. By edge detection of input image and binaryzation processing of joint power spectrum, the system can achieve sharper correlation peak and location accuracy. Simulation calculation and optical experiments show that even in noisy background, the system can obtain excellent recognition and location performances with 16frames/s, recognition probability greater than 94%, and location accuracy better than a pixel. It is very advantageous to meet the demands of further improving performance, speed, and shoot accuracy of the cruise missiles.
