Abstract
An environmental detection method for a vehicle uses transmitting antennas to emit transmission signals that each consist of a sequence of identical or similar single signals, uses receiving antennas to receive the transmission signals reflected from objects, and processes the received signals. The transmission signals are emitted from only one transmitting antenna at a time, and the active transmitting antenna alternates cyclically from single signal to signal. All receiving antennas are always used in parallel. The received single signals are accumulated in proper phase for the different combinations of transmitting and receiving antennas to at least one relative speed hypothesis of objects. Digital beam formation is performed based on the accumulated signal values, each belonging to the same relative speed hypothesis, from different antenna combinations. Phase differences between received signals from different transmitting antennas are thereby taken into consideration.
