Abstract
A system for detecting a target, the system comprises a transceiver and a signal processor; wherein the transceiver that is configured to: transmit a first pulse train that comprises multiple radio frequency (RF) pulses of a first non-linear polarity; receive first echoes resulting from the transmission of the first pulse train; generate first detection signals that represent the first echoes; and wherein the signal processor is configured to process the first detection signals to provide an estimated polarization orientation of a target; wherein the processing of the first detection signals comprises estimating a Jones matrix of the target.
