Advancing technology has brought down the cost of 24 GHz radar system significantly bringing a whole range of new applications into reach. Historically radar was a pure military and industrial application due to high application costs. With the latest generation of NXP BiCMOS technology this has changed. A 24 GHz radar frontend can now be fully integrated into a single IC bringing the costs and power dissipation down to consumer levels. This opens up a whole range of applications which were previously not possible. This lecture will show the possibilities of radar in different applications such as presence detection and consumer drone collision avoidance. A live demonstration based on first test chips in combination with ARM processors will be given.
