Range filtering combined with suppression filtering for full-polarization characterization retention

A system for detecting targets with radar signals, the system comprising:

• a transmitter configured to transmit orthogonally-polarized incident radar signals;
• a receiver configured to receive a radar signal on orthogonally-polarized channels and generate a receiver return vector having four elements representing four channels of a full-polarimetric radar reading;
• a range filter configured to filter reflections in the receiver return vector at a selected range bin;
• and
• a polarization filter configured to filter an identified interference signal from a return of the range filter.

A method for detecting targets with radar signals, the method comprising:

• receiving a radar signal on orthogonally-polarized channels by a receiver to generate a receiver return vector;
• filtering reflections in the receiver return vector at a selected range bin by a range filter;
• and
• filtering an identified interference signal from a return of the range filter by a polarization filter.
