基于STK/Matlab的雷达对抗场景动态可视化仿真研究

战前进行雷达对抗场景的仿真推演能够有效地节约演习成本.利用STK和Matlab两种软件对雷达对抗场景的动态可视化仿真进行了研究.按照雷达对抗场景要求,首先给出了目标雷达模型和跨周期相位调制干扰模型;然后提出了一种雷达对抗场景的动态可视化建模方案;最后给出了干扰机对目标雷达实施干扰过程的动态可视化建模和干扰效能的仿真分析.仿真结果表明,动态的雷达对抗场景下,跨周期相位调制能够实现航迹欺骗干扰,当运动目标靠近干扰航迹或与干扰航迹重合时,雷达将无法对目标信号进行有效检测.

Research on dynamic visualization simulation of radar countermeasure scene based on STK/Matlab

Simulation and deduction of radar countermeasure scene before war can effectively save the exercise cost.This paper utilizes STK and Matlab to study the dynamic visualization simulation of radar countermeasure scene.According to the requirements of radar countermeasure scene,the paper firstly constructs the target radar model and the cross-period phase modulation interference model,and then proposes a dynamic visualization modeling scheme of radar countermeasure scene.Finally the paper conducts the dynamic visualization modeling of jammer interfering with target radar and makes a simulation analysis on jamming efficiency.The simulation results show that cross-period phase modulation can achieve track spoofing in dynamic radar countermeasure scene,and that when the moving target is close to or overlapped with the disturbance track,the radar will not be able to detect the target effectively.
