Abstract

The principle, design and experimental results of a simple direct imaging radar sensor are presented. The FM-CW radar principle and a frequency scanned antenna are combined with waveforms of different frequency slopes in such a way that angular and range information are provided by the amplitude envelope of a fixed video frequency. The sensor architecture uses a minimum of active RF components and digital signal processing. With low cost frequency scanned antennas, this architecture can be applied in radar surveillance stations or automotive side looking sensors.
