An Improved High-Resolution Parameter Estimation Algorithm Incorporating Beamforming Techniques

When the conventional Space-Alternating Generalized Expectation-maximization (SAGE) algorithm is used to estimate the incident angle of the signal received by an antenna array with fixed aperture, the accuracy and resolvability of angle estimation are affected and limited by the aperture of the ante...
