함정용 레이더의 모노펄스 위상 정합에 대한 연구 = A Study of monopulse phase align for a ship's radar

다국어 초록 (Multilingual Abstract)

Mordern radars has a monopulse method to improve angular accuracy. In order to use the monopulse method, phase matching, phase matching data should be measured in the production process for compensating the phase difference between sum and del channel. The phase matching measurement is performed with the antenna fixed under far-field condition. Phase matching data is essential for using the monopulse method and re-measurement is required when replaceing major units. In the case of radars mounted on ships, maintenance of factofry is limited. This is because radar is optimized and mounted on of building the ship. Therefore, only factory-incoming maintenance of the antenna unit mounted on the outside is performed. In this process, phase matching data must be measured again under a maritime environment condition. The marine environment cannot satisfy far-field condition with the fixed antenna as vibration and limited measurement positon of the ship by sea level. In this papaer, a method of measuring phase matching data in a marine environment mounted on a ship was proposed, and its effectiveness was verified.
