SAR imaging in an automotive scenario

In this paper a 77 GHz patch array radar is used in combination with the line processing and range Doppler algorithms to produce synthetic aperture radar (SAR) images of automotive scenarios. Measurements are made using a linear rail unit and the images are briefly discussed. In the latter part of the paper, a position error investigation is carried out, where the measurements are customised to fit a real automotive scenario where the automobile experiences acceleration errors which are not detected by the acceleration sensors fixed in the car. The images with errors are then presented and a quantitative analysis is carried out.
