Application Number: JP,2025-127119

Category (FI): G01S13/95,G01S7/02,210,H01Q3/26@C

Stage: PROBLEM TO BE SOLVED: To form such a transmission/reception beam pattern by real time processing without beam width degradation that a clutter is suppressed in its electric power distribution direction while a target is extracted in a desired direction in a radar device (not limited to metrological uses) using an array antenna.SOLUTION: The present disclosure acquires information on electric power distribution of a clutter and then calculates such a reception excitation coefficient of each element that a reception beam pattern forms a main lobe in a desired direction while forming a null in the electric power distribution direction of the clutter. Meanwhile, the present disclosure acquires information on electric power distribution of a clutter and then calculates such a transmission excitation coefficient of each element that a transmission beam pattern forms a main lobe in a desired direction while forming a null in the electric power distribution direction of the clutter.SELECTED DRAWING: Figure 4 (Grant)
