Spectral estimation and direction-of-arrival (DOA) estimation is considered for discrete lens antenna array front ends. In this approach, when using the Multiple Signal Classification (MUSIC) algorithm, the dimension is reduced by the front end which performs spatial processing, resulting in increased computational speed and decreased computational load. As a specific example, simulations of a 33-element lens array with DOA estimation for 7 simultaneous sources shows that the computational load is reduced to 68     «
