Scanmatic - Sonar Transponder Module (STM) - Brochure

Scanmatic’s Sonar Transponder Module (STM) receives and analyzes audio signals from sonars, and generates an echo or emits pre-stored audio signals. In “echo repeat”, STM adds a signature to the received sonar pulse and sends back this modified audio pulse. For a sonar operator, it looks like there is a real submarine on the sonar screen.
