Patent ID: 8482455

Claim:
A radar device comprising: in transmission, a coloured transmission system comprising at least two contiguous antennas, the first antenna transmitting a first code and the second antenna transmitting a second code, the two codes being mutually orthogonal; filtering means separating the received signals into two signals R 1 and R 2 , the signal R 1 corresponding to the first code and the signal R 2 corresponding to the second code, a first measurement of the angle of arrival of the target echo being obtained by applying the single-pulse measurement principle to the two signals R 1 and R 2 , said second measurement having a measurement accuracy and an ambiguity level; in reception, an interferometer comprising at least two receiving antennas, supplying a phase measurement and therefore a second measurement of the angle of arrival of a target echo, said first measurement having a direction accuracy and an ambiguity level; the measurement retained for an angle of arrival of a target echo having the direction accuracy of the second measurement and the angular ambiguity level of the first measurement.
