Optimizing Two-Tone Spurious-Free Dynamic Range for Polarimetric Agile Radar Receivers

The PARSAX - Full polarimetric FMCW radar with dual-orthogonal signals
Conference paper (2008) - O.A. Krasnov, L.P. Ligthart, Z. Li, EP Lys, W.F. van der Zwan
The article describes the IRCTR PARSAX radar system - fully polarimetric FMCW radar with dual-orthogonal sounding signals, which has the possibility to measure all elements of the radar targets polarization scattering matrix simultaneously, in one sweep.@en

Design considerations of the RF front-end for high dynamic range digital radar receivers

First demonstration of an X-band airborne FMCW SAR

Branch correlation measurements and analysis in an indoor raleigh fading channel for polarization diversity using a dual polarized patch antenna
Spatial diversity techniques are advantageous if the received signals of the diversity branches are sufficiently uncorrelated. Theoretical study using the power unbalance between the two branches employing Laplacian direction of arrival (DOA) distribution is carried out. It is sh ...

Radar system concept for simultaneous BSM of complicated and non-stable targets measurements
Conference paper (2005) - ME Rovkin, VA Khlusov, L.P. Ligthart, W.F. van der Zwan
The algorithms of the signal processing and the functional scheme of the polarization radar with simultaneous back scattering matrices measurements are givenin this paper. The radar is destined for low atmosphere remote sensing.@en
