함정용 전자전장비는 적의 대함위협으로부터 아군함정을 보호하는 장비이다. 현재 해군에서 운용 중인 함정용 전자전장비는 2000년대 초반에 전력화되어 현재까지 사용되고 있다. 이 장비에서 레이더 신호를 수신하고 분석하는 수퍼헷수신장치는 가장 중요한 장치 중 하나이다. 수퍼헷수신장치의 핵심 부품인 동조기(RF Tuner)는 해외 기술 용역으로 개발되었으나, 기술의 진부화, 도입을 위해 소요되는 시간 및 부품 가격 상승으로 국산화 개발의 필요성이 대두 되었다. 이에 진부화 된 기술 문제를 해결하기 위해 기존 아날로그수신 방식에서 디지털수신 방식을 적용하여 기존 대비 향상된 성능의 전자전용 디지털 신호수신장치를 개발하였다. Electronic warfare equipment for ships is equipment that protects friendly ships from enemy ships against threats. The electronic warfare equipment for ships currently in operation in the Navy was deployed in the early 2000s and is still in use. Superheterodyne receiver is one of the most important equipment that analyzes radar signals in this system. The RF Tuner, which is a key component of the Superheterodyne receiver was developed relying on foreign technology service, but domestic development was required due to the obsolescence of technology, delivery time and increase in part price. Accordingly, in order to solve the obsolete technical problem, signal receiving equipment with improved performance compared to the previous one was developed by replacing an analog receiver with a digital receiver.

Purpose: This study identifies the appropriate signal data from an electronic weapon system for in a prognostics and health management (PHM) technique, and suggests a design idea for efficient data collection. Methods: The RF module of a signal process unit was selected for applying a PHM technique. The current signal and RF signal were collected by the measurement equipment for 120 days, and the remaining useful life (RUL) was predicted using three parameters: current, RF, RF signal, and combination of current and RF signal. Results: Both sets of collected data showed a degradation trend over time. Three RUL predictions that were based on cumulated data over 80 days approached the actual failure point. However, the respective predictions were very different during the early portion of data collection. Additionally, this study suggests a design idea for efficient and economical data collection by embedding the RF detector and current sensor within the RF module. Conclusion: This study demonstrates the possibility of applying PHM to an electronic RF module based on its signal degradation trend. The suggested data collection and RUL prediction-methods from this study can be applied to various electronic weapon systems.
