Range-azimuth tracking of humans using a microstrip leaky wave antenna

We investigate the concept of using a simple microstrip leaky wave antenna as a radar front-end to achieve range-azimuth tracking of humans. The frequency-scanned beam of the antenna and its frequency bandwidth are exploited to achieve simultaneous direction-finding and ranging within a single frequency sweep. As a result, a two-dimensional range-azimuth image can be readily generated. The radar processing algorithm is described. Human tracking measurements are carried out to demonstrate the performance.
