Abstract :
Polarization parameters and their Doppler spectrum of reflections characteristics coming from volumetric distributed radar objects are estimated for Doppler-polarimetric radar using complex modulations signal transmission the case of complex signals using. The influence of the sounding signal´s ambiguity function on the possible joint estimation of the velocity spectra and separate backscattering matrix elements of objects is shown. Simulation results of our algorithms estimating the matrix Doppler spectrum are presented for the case of PCM and LFM transmissions.
