Abstract

A modified improved LMS algorithm is used for active cancellation of probing sources in arbitrary linear dipole array. The mutual coupling is included in the formulation of the received signal vector and hence weight adaptation. The signal environment consists of the multiple narrowband uncorrelated desired and probing sources. The dipole array performance in adaptive nulling is analyzed in terms of output signal-to-interference-noise ratio (SINR) and adapted pattern. It is shown that parallel-in-echelon dipole array is able to maintain multilobe beamforming with accurate and deep nulls towards each probing source.
