On Key Techniques of a Radar Remote Telemetry and Monitoring System

In order to monitor those vessels which are not equipped with AIS, a radar remote telemetry and monitoring system which combines radar and ECDIS is proposed. This system consists of data collection layer, processing layer, and presentation layer. Each radar station is installed with MD-3641/3642 radar. Using the 16-bits SCM PIC24 as CPU, an embedded hardware based on ETX PC is designed for radar telemetry. A logic diagram for the embedded radar controller is illustrated. Internet communication technology is adopted to complete the data transmission between center and radar station. A target echo identifying algorithm is presented to denoise the radar image and compute the accurate position of the objects overlaid on the electronic charts. Applied result shows that these techniques and approaches are efficient and feasible.
