  • A digital polarization agile monopulse de-
    tector was presented. Detection work°ow, method of
    virtual polarization synthesizing and method of digital
    monopulse angle error extraction based on variable polar-
    ization antenna with linearly polarized subarrays were pro-
    posed. Polarization agile was realized by utilizing digital
    controlled phase shifters in multichannel T/R module. The
    gain of antenna array can be improved and the beamwidth
    of cross polarization less than ¡15dB can be widened by ap-
    propriately increasing the number of subarray. The mea-
    sured results show the availability of the detector and the
    e®ectiveness of virtual polarization synthesizing and digital
    monopulse angle error extraction method.
