Infrared Cooperative Target Group for Opto-electronic Landing Guidance

为了实现舰载机全天候自主着舰,本文研究了舰载机光电导引着舰用红外合作目标组合。首先提出了切实可行的工作过程及地面车载验证方案,然后研制了合作目标。根据大气窗口、红外辐射在大气中的传输特性和待选波段对应的最佳辐射温度对合作目标温度控制的影响,确定了8～14μm波段为合作目标对应的辐射波段。根据摄像机的探测距离的估算以及实际要求确定了合作目标的大小。将所设计的合作目标组合用于光电导引算法,计算结果表明,对着舰点的位置预测误差分别小于0.5m、1m、1.2m,具有很高的精度。

For the purpose of implementing carrier-based aircraft landing on the deck of carrier automatically under all-weather, a kind of infrared cooperative target group was proposed. Firstly, landing scheme based on cooperative target was arranged and a kind of cooperative target group was developed. According to the atmospheric window, transmission property of infrared irradiation in atmosphere and the impact of the most appropriate temperature corresponding to the optional infrared band on the controlling of the cooperative target＇s temperature, 8-14μm was identified as the radiation band of the cooperative target. The dimension of cooperative target was decided by detection distance of infrared imaging system and requirement. The result shows that landing points forecasting position error of three dimensions are less than 0.5 m, 1.0 m, and 1.2 m, respectively. Opt-electronic landing guidance algorithm has the characteristics of high precision by using cooperative target group.
