ABSTRACT:
A multitransmitter RF rotary joint free weather radar system is used to transmit two transmitted waves toward an object and to receive two reflected waves from the object. The system incorporates an antenna pedestal having a platform support and a platform. The platform support is attached to a base. The platform is rotatably coupled to the platform support. A reflector is in electromagnetic communication with a coherent transmitter subsystem, a first channel subsystem, a second channel subsystem, and an analyzer subsystem. The subsystems rotate with the platform and reflector. RF rotary joints are not utilized. The coherent transmitter subsystem generates radio signals that are modulated by the two subsystems to create the two transmitted waves. Two receivers process the reflected waves. The analyzer subsystem is in wireless communication with a remote computer.
