レーダ装置。 In a phased array radar device that detects and tracks targets by arranging multiple phased array antennas close to each other, this method adds a discrimination pulse having a unique frequency to the transmitted wave of each antenna. a discrimination pulse generator, and a filter for selecting received waves due to radio wave interference from other antennas using the discrimination pulse of the received waves.
A phased array radar device characterized by being equipped with a wave detector, a pulse width discrimination circuit, a gate circuit, and a filter for removing discrimination pulses using selected received waves, and eliminating radio wave interference between multiple antennas. .
