基于弹道数据的弹星通信链路仿真

Simulation of Communication Link between Missile and Satellite Based on Ballistic Trajectory Data

建立弹星通信链路,可以有效提高武器系统与指挥控制平台之间的实时双向数据通信能力,进而增强导弹的目标识别能力、提高其打击的突发性和命中精度。使用通用的模块进行参数配置对通信链路进行模拟,仿真结果的精确性和真实性有限。为解决上述问题,在通用的通信链路建模基础上增加具体的弹道数据文件和计算模块完善仿真系统,可以更加精确实现对弹星通信链路的模拟,利用matlab/simulink仿真软件进行建模和参数配置,搭建起完整的弹星通信链路模型,并对子模块进行了仿真验证。利用的导弹弹道数据、考虑链路预算的天线方向图数据、中继卫星位置等信息,通过仿真获得导弹整个飞行过程中的通信链路情况、通信信道特征、接收端信号的多普勒频移等数据,提高了仿真结果的准确性和真实性。

Real-time bidirectional data ability between weapon system and command and control platform can be improved by establishing the communication link between the satellite and missiles. In this way, the target recongnition ability and accuracy of the missiles can be also improved. The accuracy and authenticity of the simulation are not enough by simulating the communication link with parameter configurated common modules. This paper gave the complete communication link modules by modeling and parameter configuration based on software of matlab/simulink, and carried out the test and verified the modules. With the real ballistic trajectory data, Antenna Radiation Pattern and information of Tracking and Data Relay Satellite, real communication channel characteristics and Doppler Shift can be obtained, and the accuracy and realness can be increased.
