The KoçSavunma Wake Detector is a high-frequency active sonar system which is attached to underwater platforms/weapons for detecting the presence of surface platforms from their wake. For this, the wake in the form of micron-sized air bubbles created by the propeller and hull cavitation of surface platforms that can reach a certain depth are used. The system detects the wake and measures its thickness. It sends a high-frequency acoustic signal through the transducer to detect the wake track and to process the returning acoustic echo.
