摘要：
This paper proposes a novel scheme suitable for mm-wave automotive radars to estimate the direction-of-arrivals (DOAs) of coherent waves with only three receiving antennas. Reflected waves completely correlated from two targets can be resolved with calibrated 3-channel array antenna by using only one snapshot data. The resolution capability can be further improved with the use of multiple snapshot data. A 77GHz prototype radar mounted on a vehicle successfully measured the directions of two stationary targets in real time computation.
