Patent ID: 7623064

Claim:
A method for developing information about objects that reflect electromagnetic signals that reach the objects, comprising the steps of: transmitting a first signal in a first polarization mode and a second signal in a second polarization mode, where the first polarization mode is orthogonal to the second polarization mode; transmitting a third signal in the first polarization mode and a second signal in the said second polarization mode; receiving a fifth signal having said first polarization mode that results from said first signal and from said second signal, a sixth signal having said second polarization mode that results from said first signal and from said second signal; receiving a seventh signal having said first polarization mode that results from said third signal and from said fourth signal, an eighth signal having said second polarization mode that results from said third signal and from said fourth signal; processing said fifth signal, said sixth signal, said seventh signal and said eighth signal together to create said information about objects; and employing the created information to characterize object that produced said fifth, sixth, seventh and eighth signals.
