Abstract

A beam pattern of a radar is measured at a specific facility such as an anechoic chamber, and it is difficult and expensive to move a physically large radar from an operating environment to the facility. If a radar can measure beam pattern characteristics with landmark or celestial bodies in an operating environment, it can provide a cost effective maintenance. Sun is a celestial body which exists in an operating environment, and sun noise is easy to monitor automatically. However, interferences interfere with the automatic detection of noise. Therefore, in this study, we implemented and tested an automatic sun noise monitoring method and an effective interference suppression method in a radar operating environment.
