1. A weather radar system, comprising:

  • a. an energy pulse train generator for producing radio emissions adapted for weather radar use;

    b. a radio frequency power divider in electrical communication with said pulse train generator for splitting said radio emissions into simultaneous dual emission components;

    c. an antenna in electrical communication with said power divider for transmitting said simultaneous dual emission components into space in a controlled manner and for collecting reflected signals from objects of interest;

    d. an orthomode feed horn positioned on said antenna for altering one of said emission components to have a different phase relative to said other emission component during transmission and for collecting reflectivity signals of disparate phase relative to one another;

    e. a receiver subsystem in electrical communication with said antenna for processing reflectivity signals collected by said antenna;

    f. wherein said receiver subsystem is co-located with said power divider to reduce phase error introductions; and

    ,g. a pair of channel circulators in electrical communication with said antenna, said power divider, and said receiver subsystem for isolating said dual emission components from said receiver subsystem.
