METHOD FOR REPRESENTING RADAR IMAGES OF AN AREA OF ACTION UNDER SURVEILLANCE

摘要

According to the invention a stationary radar system covering an area of action to be placed under surveillance, such as an airport, seaport or river port, generates radar images. Onto each radar image of the area of action under surveillance which is generated by means of the radar system an optical image (aerial image) of the same area of action is superimposed by means of a data processing system. The combination image of the area of action obtained by this superimposition is transmitted to an observation and surveillance platform of a tower and from there to receiving monitors of moving targets in the area of action and represented on same. From the plurality of moving targets of a combination image the current position of, and possibly also a part of the path already travelled by, a moving target can be shown (by afterglow) on its receiving monitor by means of a differential GPS receiving unit which is assigned to said moving target and with which it can connect.
