Monopulse Secondary Surveillance Radar Antenna Theory

摘要

This article brings clarifications regarding the implementation of a Monopulse Secondary Surveillance Radar (MSSR) antenna. The calculations focus on SUM beam patterns in the radar-aircraft dialogue. The novelty is the determination, by calculation, of the vertical SUM beam pattern. For the chosen antenna design, the same working algorithm can be applied to determine the CONTROL and DIFFERENCE beam patterns.
