Abstract.
The design issues of monopulse frequency-scan waveguide antenna array for terminal
area radar of X-band are discussed. A monopulse antenna, which consists of waveguide
emitters, connected to the waveguide feeding system, is designed to form the
sum and difference patterns in the frequency scanning plane. In the orthogonal
plane the antenna forms a cosecant type patterns. The features of proposed
antenna with serial feeding of radiators are researched, the methods, which allow
eliminating typical disadvantages, are presented. The computer model numerical
simulation results and measurement results of antenna prototype radiation
patterns on the near field test stand are given. A comparative analysis of the
experimental characteristics with simulation results is performed. Combination
of technical solutions has allowed providing high-quality electrodynamic
characteristics of developed antenna.
Key words:
monopulse antenna array, frequency scanning, pattern, waveguide feeding system,
numerical simulation.
