An Antenna Array Synthesis for Large Vertical Aperture Antenna for Secondary Surveillance Radar

Abstract

This paper briefly deals with a structure of a Signal distribution network for a Secondary surveillance radar. Three typical radiation beams (Sum, Difference and Control) are described. The antenna array synthesis of a Sum beam is performed. The structure of a critical part of a horizontal signal feeder (Central distribution network) is described. This part allows to create a Difference and a Control beams. The sensitivity analysis of the impact of the variations of amplitude of a signal at the outputs of the horizontal distribution network and sensitivity analysis of the impact of the variations of phase of a signal at the outputs of the horizontal distribution network are performed.
