摘要/Abstract

摘要： 针对近程来袭目标方位全向精确探测问题，基于激光近程探测理论和磁近感理论，提出了光-磁复合方位测量方法。建立了近程探测脉冲激光信号模型和旋转扫描等效磁荷数学模型。利用Monte Carlo仿真实验方法，研究了方位角测量统计分布规律，分析了传感器与磁芯间距、旋转扫描探测周期和信号检测阈值对方位角测量统计分布规律的影响。结果表明：方位角测量概率密度分布随着传感器与磁芯间距的增加向左迁移，且半峰全宽增大，均值偏离真实值；测角分布峰值随着旋转扫描转速的增加而变大且向较大的角度移动；随着阈值增加，测角分布变得集中，达到最大值后趋于分散，峰值前后测角分布曲线呈现出不同的上升沿和下降沿。

Abstract: For the omnidirectional precise detection problem of short-range incoming target, a method of laser-magnetism combination azimuth measurement is proposed based on laser short-range detection theory and magnetism proximity sensation theory. The short-range detection pulse laser signal model and rotational scanning equivalent magnetic charge mathematical model are established. The Monte Carlo method is used to study the statistical distribution of azimuth measurements in the simulation experiment. The influences of sensor-to-magnetic core spacing, rotation scan detection period and signal detection threshold on the statistical distribution of azimuth measurements are analyzed. The results show that the probability density distribution of azimuth measurement shifts to the left with the increase in the distance between the sensor and the magnetic core, the full width half maximum increases, and the mean value deviates from the true value; the peak value of angular distribution increases with the increase in the rotating scanning speed; as the threshold increases, the angular distribution becomes concentrated, thus reaching the maximum and then tending to disperse, and the front and back angular distribution curves show different rising and falling edges.Key
