本文给出一个章动扫描的红外导引头和非扫描的脉冲激光导引头的组合导引头。目标的红外和激光能量经过会聚透镜系统到达装在旋转舵螺稳定平台上的楔形的滤光片上。滤光片的前表面反射激光能量,倾斜的后表面反射红外能量,从而使红外和激光能量分开。激光能量被聚于四象限光电池上并被探测。红外能量通过光电池传到脉冲编码的调制盘上,之后,脉冲编码的红外能量由另一个透镜聚于红外探测器上。 In this paper, a combined seeker with a non-scanning pulsed laser seeker and a nutation scanner is presented. The target’s infrared and laser energy are passed through a converging lens system onto a wedge-shaped filter mounted on a rotating platform. The front surface of the filter reflects the laser energy and the sloping rear surface reflects the infrared energy, separating the infrared and laser energy. Laser energy is concentrated on four quadrant photocell and probed. Infrared energy passes through the photocell to the pulse code modulation disk, after which the pulse-coded infrared energy is focused on the infrared detector by another lens.
