CONDITIONS TO THE RADAR VECTOR SIGNAL PROVIDING SIMULTANEOUS MEASUREMENTS OF ALL BACK-SCATTERING MATRIX ELEMENTS

摘要

Properties of the illuminating waveforms and conditions to the signals, forming orthogonal (by polarization) vector sounding signals are discussed in the paper. These signals are needed in order to estimate the back-scattering matrix (BSM) of real media and objects. It is shown that the correct BSM estimation of fluctuating objects, having a-priori unknown ranges and radial velocities, is possible only when complicated orthogonal signals are being used. The principles of forming the needed radar waveforms as well as principles of back-scattered vector signal processing, assuming Gaussian noise at the receiver is formulated.
