摘　　要：提出了一种光电混合的成像制导系统，它采用光学联合变换相关器作为其主要的图像识别单元，利用计算机对识别结果进行判决和显示，并发出跟踪信号给导引头，从而实现制导。联合变换相关器是对光学图像信号进行并行处理的器件，实时识别性能强，精度高。此成像制导系统克服了传统的红外制导系统易受外界因素影响，实时处理能力差，误判率较高的缺点，具有并行处理速度快、信息吞吐量大、体积小等优点，应用前景广阔。A new imaging guidance system based on joint transform correlator is suggested in this paper. The joint transform correlator is the main pattern recognition cell and the computer is also used to analyze and display the result, and send the signal to seeker. Joint transform correlator is a apparatus to parallelly dispose the optical image signals with high real-time capability and precision. This guidance system has overcame many defects of infrared guidance system and has great advantages in fast parallel processing, great input/output data quantity, small volume, and broad prospects.
