Abstract:
Based on the spacetime adaptive antijamming technology in the global satellite positioning system, the research and implementation of the antijamming system based on MultiStage Nested Wiener Filter(MSNWF) discussed. The whole antijamming performance of the system is studied by means of the modeling of the space time adaptive processing and algorithm. Through the field test, the system can realize the function of anti jamming, and can inhibit the interference of multiple narrowband and broadband, the suppression effect is reached 50~70 dB, and the whole anti interference ability of the receiver is reached 70 dB.
Key words: space , time adaptive, multi , stage nested wiener filter, anti jamming
