摘　　要：针对环视扫描式激光成像引信探测存在着需要光机扫描和较高的激光脉冲重复频率等问题,提出了一种线阵推扫式激光成像引信探测模式并分析了其探测机理。以对坦克目标探测为例,设计了线阵推扫式激光成像引信探测系统,该探测系统采用线阵半导体激光器阵列发射脉冲激光,线阵光电探测器阵列并行接收来实现一维扫描,弹的飞行实现另一维扫描,在获取目标距离信息基础上进行成像。在对阵列单元激光脚印尺寸大小计算的基础上,确定了该探测系统的基本参数包括所需线阵元数、生成图像大小、半导体激光器阵列的脉冲重复频率和峰值功率等,为系统的工程实现提供了理论依据和设计指导。In laser imaging fuze detection technology, a linear array push-broom imaging method was proposed to solve the problem in circle-scan imaging method such as needing scanning mechanism and high pulse repetition frequency laser. The principle of linear array push-broom imaging method was analyzed in detail. Linear array push-broom imaging detection system which consists of linear diode laser array and linear photodiode array was designed to detect tank target. One dimensional scatming was performed by linear array device itself and the other one dimensional scanning was performed by forward velocity of the munition. The image of target was generated based on range information. Basic design parameters of the system including the number of array elements, the size of the image, the pulse repetition frequency and the peak power of linear diode laser array, were chosen based on the calculation of the element laser footprint size. The methods of choosing basic design parameters provide guideline for hardware realization of the system.
