空袭目标典型航迹模型的设计与仿真实现

为有效和逼真地模拟雷达接收点迹数据,再现空袭目标航迹变化情况,为雷达操作手提供虚拟条件下接近真实的战场环境,建立了空袭目标直线、圆弧、大S线3种典型航迹模型,利用地理信息系统(Geography Information System,GIS)提供的电子地图和军队标号进行了仿真实现.采用"隔三取一法"解决航迹参数网络传输实时性问题;以四机编队为例具体阐述了航迹参数的实时记录和镜像变化问题的解决办法;采用时间迭加,递推计算的方法实时显示目标运动航迹,满足了仿真要求.实践证明,模型简单,可操作性强,适合中小型雷达对抗训练模拟系统中空袭目标模块的仿真实现.

Design and simulation of aircraft typical track model for air attacking

In order to simulate dots data of the air-attacking aircraft received by radar effectively and realistically,reappear the changing of the aircraft track,and provide nearly actual battlefield environment for the radar operator,we built up three typical track models of the air target,beeline,arc and fold line,and used the electronic map and military tabs provided by Geography Information System(GIS) for simulation.We used"taking one at an interval of three"method to solve the real-time problem of network translating of the track parameter.Taking the formation of four aircrafts as example,we presented the method for real-time track parameter recording and the solution of the mirror changing of the aircraft.The methods of time superposition and recursive calculation were used for displaying the moving target track in real time,which satisfied the simulation requirement.Practice proves that the model is simple,operable,and suitable for simulation implementation of the air target module in the middle/small Radar Countermine Training-Simulation System(RCTSS).
