SIMULTANEOUS DUAL POLARIZATION RADAR SYSTEM

Title:

SIMULTANEOUS DUAL POLARIZATION RADAR SYSTEM

Document Type and Number:

WIPO Patent Application WO2004086075

Kind Code:

A3

Abstract:

A simultaneous dual polarization radar system is disclosed that utilizes a RF power divider (21) to replace the high speed dual polarization switches (17) utilized in current dual polarization radar systems. The disclosed systems allow for transmission and reception in both horizontal and vertical signal modes simultaneously while repositioning critical receiver components (37, 38, 24) above the elevation rotary coupler (34) in a radar pedestal (16). A bypass switch (25a,b) is also utilized to allow for mode switching of a radar system and a dual polarization reception design (55) is disclosed to allow for the economical capturing of linear depolarization ratios of selected atmospheric areas. These new designs eliminate the current problems experienced in current dual polarization radar system of long dwell times and velocity range reductions, and the elimination of the relatively expensive and unreliable polarization switch (17).
