The ground based mobile perimeter surveillance of many military and civil infrastructures to detect and track potential threatening targets on ground or in the air is still a very important capability of sensor systems. Such dangerous targets can be suicide attackers or drones, which violate the privacy of individuals or which can be used for spying, smuggling, or acts of terrorism. To demonstrate the possibilities of current technologies and processing methods, a high performance mechanically scanning surveillance radar sensor and a high-resolution camera were successfully combined for these applications. Both sensors have a high measurement update rate of up to 1.6 Hz. The most remarkable feature is the use of a 94 GHz radar sensor with 3D localization, georeferencing, extended Doppler analysis, RCS calibration and multi target tracking for stand-off monitoring in real-time of an area of interest. Furthermore, the real-time images of the multi-sensor system are transferred from the operator's computer to several mobile devices to disseminate an overview of the situation. The implementation of the real-time data processing and the real time data visualization plus the intuitive system control was done successfully. The stored radar and camera data can be used for the conservation of evidence, for further offline processing and for algorithm development.
