Configuration of a Monopulse Antenna Assembly for Small Diameter Flight Vehicle Applications

Abstract

In this letter, configuration of a monopulse direction-finding (DF) antenna assembly is presented which can be applied for small diameter flight vehicle applications. The assembly consists of five antennas which consist of four radome mounted antennas and a slot fed cavity antenna. All antennas are located inside of a tangent ogive radome of 1.52 λc inner radius where λc corresponds to the wavelength of the center frequency. To verify the DF performance of the antenna assembly, sum (Σ) and delta (Δ)-patterns are measured and its Δ/Σ monopulse curves are presented.
