针对空空导弹激光引信易受云烟雾、地海杂波干扰的问题, 提出了一种适用于空空导弹的激光灰度成像引信技术。采用推扫式线阵成像探测方式, 即随着弹目交会运动并根据激光回波幅度对目标逐行扫描灰度成像。通过渐进式目标识别算法处理逐行累积而成的灰度轮廓像可实现激光引信精细化探测, 从而提高其抗干扰的能力。原理样机试验验证数据表明, 激光灰度成像技术可较好地运用到激光引信中, 验证试验获取的图像、数据, 为激光引信抗干扰研究提供了技术储备。

Aiming at the problem that air to air missile laser fuse is easily interfered by cloud, smoke and ground sea clutter, a laser gray imaging fuze technology for air to air missile was proposed. The push broom linear array detection method was used, which was progressive scanning gray imaging with the intersection motion of missile and target according to amplitude information of laser echo. The progressive target recognition algorithm was used to deal with the gray outline image accumulated by line to realize the precise detection of laser fuze, so its anti-interference ability can be improved. The test results of the prototype show that the scheme of the laser gray imaging fuze technology is feasible, the hardware realizability is high, and the image data obtained from the test can provide technical reserve for anti-jamming research of laser fuze.
