Effects of Element-Level Amplitude Quantization on Broadband Beamforming in the Presence of Sinusoidal Interference.

摘要

The effects of element-level amplitude quantization on broadband beamforming in the presence of sinusoidal interference propagating across the array is investigated using vertical array data from an October 1985 experiment 350nmi west of San Diego. FFT postprocessing of the beamformer output is included to remove (partially) the rich harmonic content of the quantized interference. The detectability of a signal in the data is investigated for various degrees of quantization of the element-level data and various levels of the sinusoidal interference.
