Abstract
A radar including a plurality of reception antennas corresponding to a plurality of homodyne reception channels, and a transmission antenna positioned with respect to the plurality of reception antenna such that a distance between the transmission antenna and each consecutive reception antenna of the plurality of reception antenna respectively increases from one reception antenna to the next. Also included is a beam-formation mechanism associated with the plurality of reception channels for receiving a reception signal from each of the homodyne reception channels. Further, a spacing between each reception antenna is set so as to orient a homodyne leakage in a direction located in an angular zone of space not processed by the radar.
