UWB MIMO Radar Arrays for Small Area Surveillance Applications

This paper addresses the issue of selection of an UWB radar array with multiple transmit and receive antennas (MIMO) for the application of small area surveillance. A comparison of classical radar arrays with a single transmit antenna and those using MIMO arrays is presented through a simulator tool. The simulator allows to define a reference 3-D scenario with a set of point scatterers, and to obtain a synthetic raw data that is then used to form a 3-D image. Different topologies have been tested, showing how MIMO antenna systems provide a narrower beamwidth, higher side-lobes rejection ration and a larger alias-free area.
