In recent years, adaptive antenna systems have been receiving much interest because of their ability to null out deliberate electronic countermeasures, friendly RF interferences, and natural noise sources. This article describes a method for improving the rate of convergence of very low frequency/low frequency (VLF/LF) adaptive antenna systems (3 to 300 KHz). Numerical evaluations show that the proposed solution can improve the system's performance by tenfold without cost penalty.
