Side lobe interference suppression with an adaptive null processor
Victor C. Anderson · The Journal of the Acoustical Society of America · 1981
Experimental data illustrates the suppression of side lobe interference levels achieved with an adaptive beamformer DICANNE (Digital Interference Canceling Adaptive Null Network Equipment). The experimental DICANNE is a 32-channel system operating broadband over a 2-octave audio bandwidth. Although the experimental nulls formed were not perfect, a 5-dB improvement in detection threshold was observed at an element interference-to-noise ratio of 0 dB.
