We propose and demonstrate an agile X-band signal synthesizer with ultralow phase noise based on all-fiberphotonic techniques for radar applications. It shows phase noise of-145 dBc∕Hz(-152 dBc∕Hz) at 10 kHz(100 kHz...
A novel matching method for simultaneous multi-target recognition is proposed by jointly considering target's prior scattering knowledge and the polarization parameters of radar echoes. The matching coefficients are c...
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 ante...
