摘要
光电瞄具提前量是指武器命中运动目标情况下,在俯仰和方位上赋予武器命中点相对于目标现在点的提前值。瞄具提前量直接决定着武器的命中精度。介绍了校验光电瞄具提前量算法的检测模型。利用建立的仿真坐标系,推导出目标航迹的参数方程;针对典型航迹,采用多项式拟合给出合理航迹点;根据所测量的方位角、俯仰角和斜距离等坐标参数和射表,用抛物线插值法推导了俯仰和方位提前量的仿真检测模型。实验证明,用该仿真模型检测光电瞄具提前量精度的方法正确可靠,为瞄具提前量的检测提供了一种新方法。
The lead of the optoelectronic sight is a lead value of weapon hitting points relative to target current points in pitch and azimuth on the case of hitting moving targets.It directly determines the hitting accuracy of weapons.A detection model for the lead algorithm of optoelectronic sight was proposed.The parameter equations of the target flight path were deduced by a established simulation coordinate system.Taking aim at the typical flight-path,we gave reasonable flight-path points by adopting polynomial fitting.On the basis of the measured coordinate parameters such as the azimuth angle,pitching angle,slant distance and fire table and so on,the simulation detection model of the lead of pitch and azimuth was deduced by using the method of parabola interpolation.The experiment shows that it is reliable to use this simulation model for detecting the accuracy of the lead calculation of the optoelectronic sight.This model offers a new method for detecting the lead calculation of the optoelectronic sight.
