Abstract:

The ASDE-3 radar antenna was developed so that closely spaced targets on an airport surface could be resolved. The requirement of accurately detecting targets as close as 500 feet from the antenna necessitated some type of near field focussing. A variable focus, shaped beam, doubly curved reflector was designed and successfully tested for this application. Additional features included an integrated rotating radome and circular polarization. Representative azimuth and elevation patterns are presented. During the development, a method for taking and plotting radiation patterns of the antenna scanning at its operational rotation rate was devised and is described. Author
