Abstract
A dual frequency radar antenna for connection to a first radar transmitter/receiver set which operates in a relatively lower frequency band and to a second radar transmitter/receiver set which operates in a relatively higher frequency band. The dual frequency radar antenna has a spherical dielectric lens having a first array of inputs coupled with the first radar transmitter/receiver set and a second array of inputs coupled with the second radar transmitter/receiver set. The spherical dielectric lens forms relatively higher frequency beams that are relatively tightly spaced about a centerline of the spherical dielectric lens while the spherical dielectric lens also forms relatively lower frequency beams that are relatively farther spaced about a centerline of the spherical dielectric lens than are the relatively higher frequency beams.
