Neste artigo, propomos um conjunto de restrições para formação de feixe de banda larga adaptativa na presença de erros angulares. Primeiro apresentamos restrições espaciais e derivadas de frequência (SFDC) para o projeto da resposta quiescente do beamformer. Com as matrizes de bloqueio baseadas em wavelets, o cancelador de lóbulo lateral generalizado (GSC) proposto preserva o sinal desejado e é menos sensível ao ruído de banda larga. Para tornar este formador de feixe mais robusto à incompatibilidade direcional, adicionamos um algoritmo de pseudo-interferência no processo adaptativo de peso. Os resultados da análise e simulação demonstram que a largura do feixe angular é insensível à relação sinal-ruído de entrada (SNR).

Abstract: In this paper, we propose a set of constraints for adaptive broad-band beamforming in the presence of angular errors. We first present spatial and frequency derivative constraints (SFDC) for the design of the quiescent beamformer response. With the wavelet-based blocking matrices, the proposed generalized sidelobe canceller (GSC) preserves the desired signal, and it is less sensitive to the broad-band noise. To make this beamformer more robust to the directional mismatch, we add a pseudo-interference algorithm in the weight adaptive process. Analysis and simulation results demonstrate that the angular beamwidth is insensitive to the input signal-to-noise ratio (SNR).
