This paper presents a novel approach for performing real-time sonar beamforming on linear sensor arrays using the MasPar SIMD architecture. The beamforming problem is defined as a three dimensional solution space by generating a cube structure with sonar array elements as one dimension, the required beams in another dimension, and the time samples in the third dimension. The given approach maps the problem cube into the MasPar structure using a modified one-to-one mapping and uses two MasPar Fortran 90 intrinsic array functions to generate the solutions to the beams. Simulation results are provided for different array and beam sizes
