Abstract
An apparatus and method for enhanced calibration of radar at the module level supports dual polarization and array calibration and alignment without the use of external test equipment. Utilizing a delay line, loop back capability at the module level allows existing receiver exciter subsystem to be used for calibration. This approach eliminates the need for manual array calibration using external RF monitor subsystem or external test antennas.
