摘要
在被动式红外检测的条件下,针对动态目标探测的可靠性及军事防卫需求,提出了一种动/静态双坐标感知探测系统。静态感知系统是一个标准的二维坐标体系,也是运动目标检测的基准;动坐标感知系统是在水平面内以恒定的角速度在90°范围内来回摆动的十字坐标系统,该系统的提出解决了传统热释电红外传感器探测感知距离与视场角成反比的矛盾,实现了全方位战场态势感知的功能。文中建立了感知系统的理论模型和数学模型。经实验验证,该理论切实可行,构建的感知系统稳定可靠,具有一定的实际应用价值。
In the passive infrared detection conditions, according to the dynamic target detection reliability and military defense needs, a dynamic/static double coordinate sensing system was put forward in this paper. Static sensing system was not only a standard-two-dimensional coordinate system, but also a benchmark of moving target detection; and moving coordinate sensing system was a cross coordinate system in the horizontal plane, swinging back and forth in the range of 90° at a constant angular speed. So the proposed system solved the problem of pyroelectric infrared sensor that perceived distance was inversely proportional to the angle of field contradictions, and it realized full range perception of battlefield. A theoretical model and mathematical model of perception system was presented. Verified by experiment, the theory, which has a certain practical value, is practicable, and the system established is reliable.
