Automotive SAR for Parking Lot Detection

In this paper a new concept for a radar based parking lot detection system is presented. The synthetic aperture radar algorithm together with a special motion compensation algorithm are implemented in a Matlab simulator for verification of the overall system. A detailed model for any motion of the vehicle is discussed and the influence of different deviations of the vehicle motion from a straight line are discussed. The simulation results demonstrate that the motion compensation algorithm together with a standard low-cost accelerometer can yield very useful images of typical parking scenes.
