摘    要:针对GPS接收系统的空时自适应抗干扰技术,讨论了基于FROST阵列处理的最小均方算法LMS——FROST-LMS(FLMS)算法.通过对时空自适应处理STAP和算法的建模,研究了该系统以及GPS接收机的性能.系统仿真表明,FLMS算法能够抑制大于阵元个数的多个宽、窄带干扰,抑制效果达到30 dB~50 dB,并使接收机整体抗干扰能力达到65 dB左右.

关 键 词:空时自适应处理  自适应抗干扰  最小均方算法  全球定位系统

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.
