摘　　要：激光模拟打靶训练器模拟环境气流角漂因素会导致控制稳定性较差,针对此问题提出红外对抗激光模拟打靶训练器控制方法。采用累积平均算法处理控制信号,计算信噪比改善值,处理控制信号中噪声,保证控制信号的信噪比水平,将处理后的控制信号拆分成数组,分别计算红外对抗激光的位置坐标X值和Y值,定位激光位置,针对有畸变的光束和没有畸变的光束,采取不同的计算方式计算控制电压,以此实现对激光模拟打靶训练器的控制。实验结果表明:设计的打靶训练器控制方法指向控制偏差小,远场标定位置准确,整体控制精度较好。The process of simulating the drift factor of air flow angle in laser simulation target training device will lead to poor control stability. The control method of infrared countermeasure laser simulation shooting training device is proposed. The accumulated average algorithm is used for processing the control signal, calculate the signal-to-noise ratio improvement value, and process the noise in control signal to ensure its signal-to-noise ratio level. The processed control signal is split into arrays, the x value and y value of the position coordinates of the infrared anti laser are calculated, respectively, and the laser position is located. Different calculation methods are adopted to calculate the control voltage of the distorted beams and the normal beams, so as to realize the control of laser simulation target training device. The experimental results show that the control method of the target training device has small pointing control deviation, accurate far-field calibration position and good overall control accuracy.
