被动式光学测距误差分析

Error analysis of the passive optical ranging

被动式光学测距系统在战场上具有隐蔽性好的特点。介绍了一种高精度被动式光学测距方法的原理和数学模型。该测量方法采用的是一种比率探测的离焦探测方法,具有高精度、高灵敏度和抗干扰性好的特点。重点分析了影响测距精度的各种因素及误差范围,为系统的设计提供了理论依据。

The passive optical ranging was not detected by the enemy on the battleground. The theory, of an optical passive ranging method with high precision and it＇ s mathematic model were introduced. The factors that affect the ranging precision and the error range are analyzed to help to design this system.
