摘　　要：现行激光射击模拟器在稍强的光背景下，接收光靶往往工作不正常．显示器出现误报．提高光靶信噪比，有效地拣出信号，成为激光射击模拟器推广应用的重要课题。该文在对激光射击模拟器接收光靶、激光信号以及噪声特性分析的基础上、针对现行激光射击模拟器存在的问题，提出将光栏滤波理论应用于激光射击模拟器中，采用干涉滤波和光栏滤波相结合等方法，提高了光靶的信噪比．Under strongger light background, the existing laser shooting simulator cannot make light target or indicator work properly. It is a main subject to increase signal-to-noise ratio of light target and pick up signals effectively so as to diffuse laser shooting simulator. Based on the analysis of the light target, the laser signal and the specific property of the noise, and considering the defects of today＇s laser shooting simulator. The paper proposed a method of applying the light diaphragm filter on the laser shooting simulator and combining the interference filter with light diaphragm. The method is very effective in raising the signal-to-noise ratio of the light target of the laser shooting simulator.
