POLARIZATION-MODULATED TRANSMITTER FOR A WEATHER RADAR

摘要

Polarization modulated transmitter, in particular for a weather radar, with at least two signal paths (3, 4) to which a radio frequency signal can be fed, and which are connected to a coupler (8), and with a phase modulation of the signal to be emitted via the antenna (1), it being possible to feed the same radio frequency signal to the at least two signal paths (3, 4) respectively having at least one transmit amplifier (5, 6), and a polarization modulator (7) is arranged for the phase modulation in one of the at least two signal paths (3, 4) in such a way that a radio frequency signal can first be phase modulated and then amplified.
