Abstract :
Based on the network theory, the equivalent parameters of a comparator cascaded with a two elements array in the single-axle monopulse radar are obtained. The influence of the reflection and coupling of the antenna elements to the reflection character of the SUM and DELTA ports of the monopulse system is studied. The results show that beside the reflection of the elements, the coupling between elements also must be considered in designing the feeding system of the monopulse system.
