Doppler radar sensor transmitting linear polarised signal in plane - carries out polarisation separation of transmit and receive signal in aerial feed

The Doppler echo reflecting objects detected move in a single plane. The sensor transmits a linearly polarised signal, processing only the reflected echo component with orthogonal polarisation w.r.t. the transmitted signal. The polarisation plane of the transmitted signal is rotated in a specified c...

Beschreibung
Zusammenfassung:	The Doppler echo reflecting objects detected move in a single plane. The sensor transmits a linearly polarised signal, processing only the reflected echo component with orthogonal polarisation w.r.t. the transmitted signal. The polarisation plane of the transmitted signal is rotated in a specified coordinate system (X, Y, Z). The polarison separation of transmit and receive signals is integrated in the aerial feed system. Pref. with an aerial, or its feed system, with a dual mode horn, the latter is extended by an ortho-mode coupler, at one gate of which the transmit signal is fed in, while the received signal is tapped at the other gate. ADVANTAGE - Simple design for movable targets.
