摘要
针对飞行武器平台攻击雷达目标进行射频仿真中的关键问题,该文建立起一种目标模拟阵列的驱动模型,在射频仿真系统中复现实际作战过程中的空间关系。依据目标与攻击武器的偏角关系,导引头、武器平台、地面及仿真环境四个坐标系间的位置关系,该文建立数学模型,确定出目标在仿真阵列上的角位置坐标;通过控制目标阵列在不同的位置辐射信号来模拟目标相对于攻击武器的空间移动,实现攻击过程的动态仿真;并给出系统控制流程;最后实验验证了模型的正确性。
In this paper, a driving method of target simulation in RFSS is described. It is established to simulate a flying weapon attacking earth - based radar in radio frequency simulation system （ RFSS）, and can represent the special relationship in actual campaign circumstance. According to the relative ubiety between the target and the seeker, and the spatial relationship among the seeker, the crankshaft, the earth and the simulation space, a mathematical model is established for mapping the ubiety concerned to the chamber of RFSS. And then the coordinates of target on the array is deduced. The radio signal which stimulates the target radar can be controlled in different locations on the array to accomplish a dynamic attacking procession. Then the system control flow is described. Finally, the simulation experiment verifies its validity.
