Antenna and electronic module support structure with rotational movement about two axes

摘要

An antenna system 3 comprises a first structure 4 attached to an aircraft which can rotate about a first axis 23 relative to the aircraft. A second structure 5 is attached to the first structure 4 which can rotate relative to the first structure 4 about a second axis 26. An antenna 28 and an electronic signal processing module are attached to the second structure 5. The first and second axes 23, 26 may be perpendicular to one another and pass through a common point. The second structure 5 may include an outer skin with a porthole radome facing the antenna 28. The second structure 5 may include a power system which is in contact with the outer skin which may include fins 29 to allow for cooling. The outer skin may be mechanically reinforced in a region facing the electronic module to provide protection for the said module. The first structure 4 may be a cylindrical member and the second structure 5 may be a spherical member. The radar support structure provides a simple, compact and robust system suitable for tactical drone deployment.
