Places which have to be monitored permanently (such as security sectors, industrial areas or power plants) are facing the problem of large-area monitoring. Optical security cameras can observe such areas under good lighting and visibility conditions, but objects might get invisible when fog, darkness or smoke reduces the visibility. This problem can be solved with millimeter-wave radars with very high slew rates of the chirp signal. The radar has a detection range of above 100m and can determine the distance and speed of objects inside the observation area very precisely. For most applications, the positon of objects is more important than their color or size.
