Dual-Band Monopulse Antenna Tracking System.
Abstract
For some time the Naval Research Laboratory has been investigating the usefulness of higher frequencies to improve the low-angle tracking of radar targets. The needs for long range acquisition and short range precision tracking were met with a combined and dual-mounted antenna system at X-band and at Ka-band. Tests of these two radars with the two antennas mounted on a common pedestal proved the usefulness of the concept. As a next step in developing a combined configuration which would be improved operationally, it was suggested that the two bands be combined into a single antenna system using only one aperture. While dual-band antennas have been used previously, the requirements for precision monopulse tracking with a common boresight at two such high frequencies made it advisable to demonstrate the technique by means of an experimental breadboard.
