Abstract

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.
