红外系统跟踪目标时,目标的位置是由目标和红外光轴间的关系来确定的;测角精度主要受两种误差源的影响——随目标辐射一起进入系统的随机背景噪声和系统内部的误差源。本文着重分析红外系统内部的误差源,精度的指标及其测量方法。
The position of the target is determined by the relationship between the target and the infrared axis when the infrared system is tracking the target. The accuracy of the angular measurement is mainly affected by two sources of error: the random background noise entering the system with the target radiation and the internal background Error source. This article focuses on the analysis of error sources within the infrared system, the accuracy of indicators and measurement methods.
