ELECTRONIC SCANNING ANTENNA WITH MULTIPLE PORTS AND RADAR USING SUCH ANTENNA |
摘要 |
The invention relates to an assembly of main and auxiliary antennas for an electronic scanning radar. Each auxiliary antenna uses all or part of the elementary radiation sources of the main antenna. The energy received by each of them is sampled by a coupler and then phase shifted by an angle phi i in an adjustable phase shift circuit. The respective outputs of the phase shift circuits are concentrated within a waveguide. The auxiliary antennas are of the same type as the main antenna. The invention is applicable to radars equipped with an anti-jamming device. |
