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.
