Abstract: To the technology on space-time adaptive anti-jam of GPS receiver system,the paper discusses least-mean-square(LMS) algorithm based on FORST array processing—FORST-LMS(FLMS) algorithm.By modeling space-time adaptive processing(STAP) and FLMS algorithm,it researches the performance of anti-jam system and GPS receiver.The simulations show the number of wideband and narrowband interferences suppressed by FLMS algorithm is more than that of the sensors of array antenna.FLMS algorithm can restrain the intensity of interference up to 40 dB~50 dB,and improve the capability of GPS receiver suppressing interference to 65 dB.
