【摘要】：折反射式周視紅外成像系統(tǒng)在安全監(jiān)視領(lǐng)域有著獨(dú)特的大視場優(yōu)勢,但是目前常見的圓錐曲面反射鏡折反射式周視系統(tǒng)存在不同俯仰角下探測距離差異大的問題。折反射式周視紅外成像系統(tǒng)的探測距離與目標(biāo)尺度、任務(wù)準(zhǔn)則、俯仰角和方位角分辨力有關(guān)。將俯仰角分辨力和方位角分辨力的幾何平均數(shù)設(shè)為常數(shù),以此作為恒等探測距離折反射式周視系統(tǒng)的條件,并推導(dǎo)了相應(yīng)的系統(tǒng)設(shè)計方法。數(shù)據(jù)仿真結(jié)果驗(yàn)證了恒等探測距離系統(tǒng)的可實(shí)現(xiàn)性,另外,也表明了所提方法不僅可以實(shí)現(xiàn)不同俯仰角下的相同探測距離,還可以通過合理的參數(shù)調(diào)節(jié)使得大部分視場范圍內(nèi)的探測距離優(yōu)于傳統(tǒng)圓錐曲面型折反射式周視系統(tǒng)的探測距離。
[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.
