Adaptive ground clutter cancellation |
| 摘要 |
The present invention refers to an airborne radar device ( 1 ) comprising at least two antennas ( 2, 3 ) and clutter suppressing means ( 4 ). The radar device is arranged, via the antennas ( 2, 3 ) to send out radar pulses focused in main lobes ( 5 ) and the antennas are arranged to receive reflecting pulses. The antennas ( 2, 3 ) are separated from each other vertically. The radar device ( 1 ) comprises means ( 6 ) for transforming the received radar pulses into complex video signals in the form sequences of range bins (R<SUB>k</SUB>). The video signals are represented in a first channel (K<SUB>1</SUB>) and a second channel (K<SUB>2</SUB>).
