摘要

低对比度动态目标捕获能力是衡量光电跟踪设备总体性能的重要内容之一。针对光电跟踪设备低对比度动态目标捕获能力室内检验方法欠缺、低对比度动态目标捕获原理尚不完善等问题,提出了实验室内光电跟踪设备对低对比度动态目标捕获能力的检验。检验采用可调对比度无穷远目标源装置和可调速转台,为被检仪器提供可准确度量对比度的光学基准目标和可准确测量速度的动态环境,根据被检设备对该动态目标的提取情况,验证光电跟踪设备的捕获能力。通过分析目标移动速度、目标大小对目标对比度的影响,评价光电跟踪设备在不同目标对比度和不同速度下的捕获性能。检验结果表明,在背景辐亮度为38 W/(sr·m2)的情况下,当直径为4 mm目标以7.45°/s以上速度从无穷远处进入某光电跟踪设备的视场时,该光电跟踪设备不能进行有效地捕获。检验结果通过光电跟踪设备对给定对比度动态目标的捕获情况来评价其整机捕获能力。

Abstract

Currently, there are some problems on indoor test methods relating to low contrast dynamic target acquisition in photoelectric tracker, and related theory about low contrast dynamic target acquisition. Because low contrast dynamic target acquisition is one of the important factors relating to overall performance of photoelectric tracker, a new indoor method for performance assessment of low contrast dynamic target acquisition in photoelectric tracker is proposed. Infinite target source of adjustable contrast and turntable of adjustable speed are considered as detection device. Optical reference target, of which the contrast can be accurately measured, is provided for detecting opto-electronic tracker working in dynamic environments where the rotation rate can be precisely set, in order to validate acquisition ability of opto-electronic tracker for low contrast dynamic object based on target extraction. The opto-electronic tracker can also be evaluated in terms of acquisition performance or acquisition speed in different target contrasts and different movement speeds by the analyses of the target′s movement speed, target size that affects target contrast. The experimental results show that the photo-electronic tracker cannot effectively capture the object of which the diameter is 4 mm entering the field of view at the rate of greater than 7.45°/s from infinity in the background of which the spectral radiance is 38 W/(sr·m2). Furthermore, the results can be applied to evaluate the acquisition ability of photo-electric tracker by a given contrast dynamic target.
