面向高速空中目标的观测设备跟踪能力需求分析

Requirement analysis of the tracking capability of observation equipment for high-speed aerial targets

为满足舰载观测设备对空中高速运动目标的有效跟踪,从空中目标运动角速度模型出发,建立了观测设备对空中目标的方位、高低跟踪死区模型,分析跟踪死区存在的条件,通过理论计算与仿真分析,明确了方向跟踪死区、高低跟踪死区与目标速度、高度、航路捷径以及观测设备跟踪角速度之间的关系:观测设备方向跟踪死区受航路捷径影响较大,高低跟踪死区受目标高度影响较大;跟踪死区大小与炮弹速度成正比、与观测设备跟踪角速度成反比。通过仿真计算给出在一定目标速度条件下,为实现对目标有效跟踪所需的观测距离或预置观测点,以满足舰载观测设备的跟踪能力需求。

In order to realize effective tracking of high-speed aerial moving targets by shipborne observation equipment,this paper establishes a model of directional and high/low tracking dead zones of observation equipment on air targets from the model of angular velocity of the air moving targets,and analyzes the conditions for the existence of the tracking dead zones.Through theoretical calculation and simulation analysis,the relationship between dead zones of both directional and high/low tracking and target speed,altitude,route shortcut as well as tracking angular velocity of the observation equipment is clarified:the directional tracking dead zones of the observation equipment are influenced by the route shortcut,and the high/low tracking dead zones are influenced by the target altitude.The size of the tracking dead zones is proportional to the projectile velocity and inversely proportional to the tracking angular velocity of the observation equipment.In order to meet the tracking capability requirements of the shipboard observation equipment,the required observation distance or pre-set observation points are calculated to achieve effective tracking of the target through the simulation under certain target velocity conditions.
