Abstract:
A method of operating a radar system including at least two antennas respectively directed to monitor respective different angular ranges in an area to be monitored, for determining at least one of a distance, angular position and radial velocity of a reflection object located in said area to be monitored, said method comprising carrying out at least one measuring process including a plurality of measuring phases, wherein:each said measuring phase comprises plural alternating transmitting operations and receiving operations;each said transmitting operation comprises emitting, from a transmitting antenna selected among said at least two antennas, a respective transmitted signal pulse having a pulse duration (t.sub.ON);each said receiving operation comprises activating a receiving antenna selected among said at least two antennas to be able to receive at least one of any reflection signals that may be reflected from said reflection object and incident on said receiving antenna during a respective pulse pause interval having a pause duration (t.sub.OFF) between successive ones of said transmitted signal pulses;in at least one of said measuring phases, the same selected one of said at least two antennas is used as said transmitting antenna in said transmitting operations and as said receiving antenna in said receiving operations; andin at least another of said measuring phases, two different selected ones of said at least two antennas are respectively used as said transmitting antenna in said transmitting operations and as said receiving antenna in said receiving operations.
