Abstract :
Global Positioning System (GPS) receiver is confronted with the serious problem what is the bad electromagnetism environment, especially, the wideband interference. Currently, nulling antenna technology is the most effective way to reject the broadband interference. The FLMS algorithm of space-time adaptive processor (STAP) is developed for the robust array antenna, and is used to estimate the beamformer weighting vector adaptively with a low computational complexity. The result of simulation demonstrates the FLMS algorithm can well suppress the broadband jammer and improve the performance of GPS receiver.
