Abstract
Unmanned Aerial Vehicles (UAVs) offer a lower risk and lower cost platform for the use of an Ultra Wide Band (UWE) Synthetic Aperture Radar (SAR) system for the detection of ground targets concealed by foliage. Given the size, weight, and power restrictions of a UAV, an impulse radar is an attractive radar system alternative because it offers a lighter and lower cost solution than a traditional chirped pulse radar system. In order to be functionally useful, the antenna system for a FOPEN SAR must meet very stringent requirements in terms of bandwidth, efficiency, and sidelobe performance. These electrical requirements must be achieved in a package that has minimal impact on aerodynamic performance. Amelex proposes to study several antennas which can meet some of the requirments. These antennas will then be further investigated, using a sophisticated computer antenna RF design package, SIGLBC, to ascertain whether any of these antennas, individually and/or arrayed, can meet all of the specifications. If unable to sumultaneously meet all of the requirements, a recommendation will be made as to the optimal approach. This approach will be reflected in the development of a preliminary design for the prototype to be fabricated in Phase II. There are numerous potential commercial applications which include the remote, non-intrusive location of structures and utilities which are concealed by foliage. The same system has the potential for ground penetration which could be used to detect underground pipelines and utility wires/conduits. The construction industries can use this technology for non-intrusive, remote inspection of road pavements, bridge surfaces, and structures,.and railroad beds for internal faults.
