介绍自适应抗干扰器抗干扰原理,并在功率倒置算法推导基础上,提出GPS卫星接收机自适应抗干扰处理器的设计实现方案。计算机仿真实现处理器所采用的自适应抗干扰算法,并分析算法的抗干扰性能。仿真结果表明,功率倒置算法适用于GPS卫星接收机抗干扰处理。抗干扰处理器的实际抗干扰能力测试结果表明,GPS卫星接收机自适应抗干扰处理器能显著提高普通GPS接收机的抗干扰能力。

The theory of adaptive anti-jamming processor is introduced in this paper。Based on the study of power invert arithmetic,a design project of GPS satellite navigation receiver’s adaptive anti-jamming processor is presented.Simulations of this adaptive anti-jamming arithmetic are done,and the arithmetic’s performances are analyzed.The simulation results indicate that the PI arithmetic can be applied in the anti-jamming processor for GPS receivers.The test results of this anti-jamming processor indicate that the GPS receiver’s adaptive anti-jamming processor can improve the anti-jamming ability of common GPS receiver.
