“…(13) The calibration matrix is then determined in a least-mean squares sense by the calculation of the pseudo inverse of the measured array response: (14) For small arrays this method provides a highly over-determined set of equations. To increase the degrees of freedom, the separation of the measured response matrix in real and imaginary part and defining a new calibration matrix C B has been proposed in [13]: To increase the degrees of freedom, the separation of the measured response matrix in real and imaginary part and defining a new calibration matrix C B has been proposed in [13]:…”

“…Esse método tem os mesmos objetivos que o método apresentado por [4], porém usa uma nova implementac ¸ão, com a vantagem de poder contar com dados externos, ou seja, tensões recebidas (calculadas ou medidas), enquanto o anterior se baseia em dados do método dos momentos. Por fim, em [6], os autores usam a mesma matriz transformac ¸ão, e aplicam o Multiple Signal Classification, (MUSIC), para determinac ¸ão da direc ¸ão de chegada, apresentando resultados experimentais para dois tipos de antenas.…”

“…Por fim, citamos Freese et al [18], que usam a mesma transformação para rede virtual em um caso em que as redes reais não têm todos os elementos iguais (redes não uniformes), e aplicam o MUSIC para determinação de DOA, apresentando resultados experimentais para dois tipos de antenas.…”
