Space-time Adaptive Processing (STAP) is usually applied to adaptive anti-jam system of Global Positioning System (GPS). It is the most effective way to reject the broadband interference. But STAP often dose matrix compute, which has a huge computational complexity. Paper investigates a recursive algorithm—Frost Least-Mean-Square (FLMS) algorithm. FLMS can reduce the workload of array signal processing and achieve real-time processing. By simulation, FLMS algorithm can not only well suppress the broadband jammer, but also suppress the number of interference more than that of the sensor elements of array antenna. FLMS algorithm makes it possibility that hardware achieves STAP.
