<p>PROBLEM TO BE SOLVED: To restrain and remove an interference wave intruded from a side lobe of a radar antenna over a wide band. SOLUTION: Respective reception signals from a main antenna 1 and an SLC antenna 3 are frequency-divided respectively by fast Fourier transformation equipment 101-102, and SLCs (side lobe cancellers) 51-5M conduct interference wave restraint for respective divided signals. The interference wave of wide band, or even the interference wave of which the frequency varies is effectively restrained and removed by the frequency division of the reception signal and only a target signal is exactly displayed on a display 6.</p> |
