A method of interior field anti-jamming test for radar seeker

提出一种基于动态坐标转换,将导弹的运动姿态变化等效到目标/干扰的运动变化,研究实现包含闭合控制回路的导引头内场静态抗干扰半实物仿真试验的方法。仿真弹道数据分析结果表明,利用基于动态坐标转换的导引头内场静态抗干扰半实物仿真方法,可以满足经过相对等效后的目标/干扰运动范围始终在电子面阵中的要求,保证静态导引头在末制导段能够随导弹运动姿态变化动态跟踪目标和实施干扰对抗。

Based on the dynamic coordinate transformation,the change of missile's motion attitude is equivalent to the change of target's motion,and the hardware-in-the-loop simulation test method for static anti-jamming of seeker's interior field with closed control loop is studied.The results of simulation trajectory data analysis show that the static anti-jamming hardware-in-the-loop simulation method based on dynamic coordinate transformation can satisfy the requirement that the moving range of the target is always in the electronic array after relative equivalence,and ensure that the static seeker can dynamically track the target and implement jamming countermeasure with the change of missile attitude in the terminal guidance phase.
