    Abstract: A radar system uses multiple-beam maximum likelihood estimation (MLE) during both search and tracking operations. During search, a four beam sequential beam cluster may be used to search for targets in a region-of-interest. During tracking, a three beam triad may be used to track one or more detected targets. In some embodiments, a beam selector switch may be used to allow two offset receive beams to time share a beamformer output port to generate the four beam sequential cluster.

    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.
