摘要

捕获、跟踪、瞄准系统精跟踪探测器在不同噪声下对精跟踪系统进行光斑位置定位的影响不同。分析了探测器条状噪声的来源, 理论推导了条状噪声对质心算法的影响。采用阈值质心算法对含有条状噪声和椒盐噪声的图像进行光斑定位, 仿真分析了不同阈值、不同光斑图像信噪比下X轴和Y轴的光斑定位偏差, 对比了X轴和Y轴的光斑定位精度。仿真结果表明, 沿Y轴方向延伸的条状噪声使得X轴光斑定位精度优于Y轴。实验分别测试了不同系统配置、不同干扰幅度下精跟踪系统X轴和Y轴的跟踪精度。实验结果表明, 对于两个正交轴对称的精跟踪系统, X轴的跟踪精度优于Y轴, 从而验证了条状噪声的存在使得X轴的光斑定位精度优于Y轴的结论, 实验结果和仿真分析结果相符。

Abstract

The noise of fine tracking detectors in acquisition, tracking and pointing systems is different, which has different influences on the position location of light spots. The source of the strip noise of detectors is analyzed, and the influence of the strip noise on centroid algorithm is deduced theoretically. The threshold centroid algorithm is used to locate the light spots of images with stripe noise and salt and pepper noise, and location deviations of X axis and Y axis corresponding to different signal-to-noise ratios and different threshold values are simulated, and the light spot location accuracies of X axis and Y axis are compared. The simulation results show that the light spot location accuracy of X axis is better than that of Y axis when the stripe noise exists in Y axis direction. The tracking accuracies of X axis and Y axis of the fine tracking system under different system configurations and different interference amplitudes are experimentally tested. It proves that, for fine tracking system with two symmetrical orthogonal axes, the tracking accuracy of X axis is better than that of Y axis, which verifies that the location accuracy of X axis is better than that of Y axis when the stripe noise exists. The results obtained from simulation and experiment are identical.
