TDMA X-band FMCW MIMO radar for short range surveillance applications

The work presented in this paper was aimed at the design of a compact radar device to be used for private area surveillance applications. The radar is connected to a pan tilt zoom camera and it provides the camera system with high accuracy position information (bearing and range) of moving targets; in this way the camera can be steered to the point of interest and automatically zoom in on the target. The idea of combining a Multiple-Input Multiple-Output (MIMO) processing approach, with a Frequency Modulated Continuous Waveform transmission proved to be the most cost efficient in order to meet the final system requirements. A test board, suitable for various processing schemes, has been developed at TNO - Defence, Security and Safety in The Hague.
