Abstract
In a radar antenna system comprising antenna elements arranged in an active array, the elements are located in predetermined groups such that an individual group can be selected electronically from within the whole array aperture, the said selection being effected by variable attenuator means. This produces a phase difference between direct and multipath reflections so that the radar information from a direct reflection can be distinguished from multipath information.
