A tour of simulation for detection & identification of targets
Rheinmetall’s Senior System Design Manager for Maritime Simulation, Klaus Meyer, walked NAVAL FORCES’ Editor in Chief & MONS Correspondent Dr. Alix Valenti, through the company’s console for command training. “This system, which runs with 30 computers for all the calculations, is used to detect targets, find out what they are and decide whether and how to engage them,” says Meyer.
It includes two posts for the sonar and one post for command and control, including weapon systems. At the sonar post, the trainees learn how to detect a target by listening to and interpreting the sounds coming from the sonar. “The first step is acoustic classification on the bottom screen, which is done by reducing the audio speed to count the number of revolutions per minute,” continues Meyer, “and, if necessary, by using the upper screen to analyse the shaft rates and blade rates (DEMON) as well as the lines of narrow band (LOFAR).”
Once the information has been analysed and the target identified, the information is passed on to the Target Motion Analyser (TMA) at the command and control post, where the distance and the speed of the target are calculated. The information is subsequently entered into the system (level of threat, type of threat, distance, etc) and passed on to the Commander who will tell command and control whether to engage or not, and how.
“Of course this is the process used for when a ship is detected, which does not require to be too fast, but if a torpedo is detected the information is immediately passed on to the Commander who then instructs command and control for weapons and helmsman as to what to do,” concludes Meyer.
