Abstract :
Current research activities in the automotive industry focus on the improvement of the perception capabilities of radar sensors. A radar sensor with four receiving antennae and its LFMSK transmit signal are introduced. To determine the DOA (Direction Of Arrival, azimuth angle) of the targets in the range of the radar sensor spatial samples of the antennae are chosen and processed using the high resolution frequency estimation technique MUSIC (MUltiple SIgnal Classification). Results of simulations and practical measurements are presented and compared.
