Agile Frequency Selection for an Antenna with Frequency Dependent Beam Firing Angle,

Abstract

This work addresses the potential problems and their solution of employing a frequency squinting antenna in conjunction with frequency agility in a naval surveillance radar system. Frequency agility is an important feature encountering enemy jamming. However, when it is applied with a frequency squinting antenna, random beam firing angle will result. This random beam firing angle causes non-uniform azimuthal coverage. Consequently detection performance in certain azimuths scanned by the antenna will be degraded. An optimization technique is employed to obtain the sequence of agile frequency selections which provides a relatively uniform azimuthal coverage, while preserving the basic random properties of the nominal sequence of agile frequencies.
