摘要：

A digital polarization agile monopulse detector was presented. Detection workflow, method of virtual polarization synthesizing and method of digital monopulse angle error extraction based on variable polarization antenna with linearly polarized subarrays were proposed. 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 appropriately increasing the number of subarray. The measured results show the availability of the detector and the effectiveness of virtual polarization synthesizing and digital monopulse angle error extraction method.
