Abstract
A system and method for processing received radar signals is presented. A steering matrix for the radar system is determined. A measurement vector is determined using signals received by a plurality of receiver modules. An output amplitude vector is initialized using the steering matrix and the measurement vector. An optimized output amplitude vector is determined by determining a diagonal loading vector using the output amplitude vector, calculating a weighting matrix using a first fast Fourier transform of the diagonal loading vector, determining an inverse matrix using the weighting matrix and an identity matrix, and executing a second fast Fourier transform using the inverse matrix to determine the optimized output amplitude vector, wherein the optimized output amplitude vector is determined by a relationship between the steering matrix and the measurement vector. An objects direction of arrival is determined by correlating the optimized output amplitude vector to the measurement vector.
