【摘要】：折反射式周视红外成像系统在安全监视领域有着独特的大视场优势,但是目前常见的圆锥曲面反射镜折反射式周视系统存在不同俯仰角下探测距离差异大的问题。折反射式周视红外成像系统的探测距离与目标尺度、任务准则、俯仰角和方位角分辨力有关。将俯仰角分辨力和方位角分辨力的几何平均数设为常数,以此作为恒等探测距离折反射式周视系统的条件,并推导了相应的系统设计方法。数据仿真结果验证了恒等探测距离系统的可实现性,另外,也表明了所提方法不仅可以实现不同俯仰角下的相同探测距离,还可以通过合理的参数调节使得大部分视场范围内的探测距离优于传统圆锥曲面型折反射式周视系统的探测距离。
[Abstract]:The refractive circumferential infrared imaging system has a unique large field of view advantage in the field of security monitoring, but the common conical curved reflector zigzag circumferential imaging system has the problem of great difference in detection distance at different pitch angles. The detection range of the refractive circumferential infrared imaging system is related to the target scale, task criterion, pitch angle and azimuth resolution. The geometric mean of pitch angle resolution and azimuth resolution is set as constant, which is used as the condition of constant detecting range refraction circumference system, and the corresponding system design method is deduced. The data simulation results verify the realizability of the system. In addition, it is also shown that the proposed method can not only realize the same detection distance at different pitch angles, The detection distance in most field of view is better than that of traditional conical curved surface refractive circumferential system by reasonable parameter adjustment.
