摘要
对自适应调零GPS导航系统的抗干扰性能进行了系统建模仿真与评估,此项抗干扰技术基于功率倒置算法。仿真结果表明,对于加装自适应调零装置的GPS导航系统,在抗干扰的过程中无需识别干扰信号来向,其抗干扰容限可达90 d B左右;对于干扰方,由于受功率、带宽的限制,单站压制式干扰的方式在实际工程中无法实现,对该系统的干扰必须采用多站干扰的方式来实现。
The anti-jamming performance of GPS navigation system with adaptive nulling based on inverted power algorithm is evaluated by simulation.Simulation results show that the anti-jamming tolerance of GPS navigation system with adaptive nulling can be90 d B and the system can resist jamming without knowing signal direction.To disrupt the GPS navigation system with adaptive nulling,high power jamming from a single station can not work in the engineering due to limitation of power and bandwidth,and multi-station jamming has to be used.
