Acoustical Direction Finding with Time-Modulated Arrays

Time-Modulated Linear Arrays (TMLAs) offer useful efficiency savings over conventional phased arrays when applied in parameter estimation applications. The present paper considers the application of TMLAs to acoustic systems and proposes an algorithm for efficiently deriving the arrival angle of a signal. The proposed technique is applied in the frequency domain, where the signal and harmonic c...

Spatial Processing with Lens Antenna Arrays for Direction-of-arrivalestimation

In this paper, spatial processing with lens antennas arrays for direction-of-arrival (DOA) estimation is considered. 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-...
