摘　　要：在给定红外探测器及其配套光源条件下,构建了能够工程实现的远距离定位中红外同步子系统。首先讨论了工程中采用的红外光学链路模型,基于系统采用的红外光源和红外探测器的性能参数,计算了红外最小可探测功率,确定了系统所需的最小红外光源功率,为系统的构建提供了理论基础,从而构建了在远距离定位中能够工程实现的红外同步子系统,并在工程中进行了验证,为远距离红外系统的构建提供了有价值的参考。Under the conditions of a given infrared detector and its supporting light source,a mid-infrared synchronization subsystem for long-distance positioning that can be realized by engineering is constructed.Firstly,the infrared optical link model used in the project is discussed.Based on the performance parameters of the infrared light source and infrared detector used in the system,the minimum detectable infrared power is calculated,and the minimum infrared light source power required by the system is determined for the construction of the system.The present study provides a theoretical basis to build an infrared synchronization subsystem that can be realized in engineering in long-distance positioning,and a valuable reference for the construction of the long-distance infrared system.
