Research on Polarization Parameter Extraction in Radar Reconnaissance

The basic theory of polarization application in radar reconnaissance is studied. Under circle polarization-base, the description form of average and instantaneous polarization parameter of radar signals based on Stokes vector estimate is deduced. The models of polarization analysis and average polarization parameter extraction are set up. A local statistical analyzing method of the polarization parameters is put forward for in-pulse polarization agility radar signal and in-pulse polarization coded radar signal. Theory and simulation prove that pulse polarization information can participate the selection and identification of radar signal to raise the ability of radar signal reconnaissance in complicated electromagnetic environment.
