Abstract:
A method for estimating a target angle of a wideband signal received on an electronically steered antenna array includes: generating spatial frequency data from the received wideband signal; stabilizing the spatial frequency data to a beam steering direction; compressing the stabilized spatial frequency data to a plurality of frequency range bins; calculating a monopulse discriminant from the stabilized spatial frequency data; and calculating the target angle using the monopulse discriminant.
