FIELD: radars, communication and moving-object control systems on board sea-going and river ships, flying vehicles, and spacecraft. ^ SUBSTANCE: proposed antenna array suited to operate under various conditions as part of radar station due to provision for enhancing values of some parameters with some sacrifice in other unused ones is convex structure made in the form of truncated tetrahedral pyramid whose top base and side faces mount subarrays; upper ribs of side faces are hinged to respective ribs of upper base which enables developing side faces into single plane with top base. In addition, this antenna array has two axes of revolution, one being horizontal (for instance, in elevation) and other one, vertical (for instance, in azimuth). Rotating developed array about these axes makes it possible to choose desired direction affording its maximal potential and definition and to organize scanning. ^ EFFECT: enlarged functional capabilities of antenna array. ^ 2 cl, 4 dwg |
