机载远程红外双站测距研究

Long distance ranging with two airborne infrared systems

介绍了红外双站测距的原理,分析了机载远程红外双站测距误差的影响因素并分别推导出各影响因素引起的部分误差公式,通过仿真实验进行了验证。实验结果表明,红外系统的测角误差和距离基线误差越大,测距误差越大;在测量精度和目标距离一定的条件下,由测角误差引起的测距误差与目标的方位角和俯仰角有关,由距离基线误差引起的测距误差与角度无关。

The ranging theory of two infrared systems was introduced. The influence factors of its ranging error were an-alyzed and the formulas of error were derived. The simulation experiments were carried out. Experimental results show that ranging error increases with the increase of angle measurement error and the baseline error; Under certain meas-urement accuracy of target distance,the ranging error caused by angle measurement error is related to azimuth angle and pitch angle of the target,and that caused by the baseline error is not related to the angle.
