Radar transceiver employing circularly polarized waveforms

摘要

A radar transceiver is disclosed which operates with circularly polarized waveforms. A single circularly polarized antenna is used to transmit and receive circularly polarized waveforms. A 3-dB directional coupler splits the signal to be transmitted into two signals 90 out-of-phase for transmission by the antenna and also combines the horizontal and vertical components of any return signal.
