Patent ID: 7355546

Claim:
A polarization diverse radar for estimating scattering matrix parameters of scatterers in a volume, comprising: a transmitter operating at a predetermined first frequency and feeding an antenna to produce a radiated signal comprising a linear combination of a first polarization, and a second polarization orthogonal to said first polarization; a transmitter operating at a predetermined second frequency and feeding an antenna to produce a radiated signal at said first polarization; a plurality of receivers, tuned to said predetermined first frequency, and an antenna to receive echo signals of a plurality of substantially orthogonal polarizations returned from scatterers in a volume illuminated by said radiated signal at said predetermined first frequency; and a plurality of receivers, tuned to said predetermined second frequency, and an antenna to receive echo signals of a plurality of substantially orthogonal polarizations returned from scatterers in a volume illuminated by said radiated signal at said predetermined second frequency.
