  • Three dimensional radar system
    Patent number: 9933519
    Abstract: A system and a method of generating a three-dimensional terrain model using one-dimensional interferometry of a rotating radar unit is provided herein. Height information is evaluated from phase differences between two echoes by applying a Kalman filter in relation to a phase confidence map that is generated from phase forward projections relating to formerly analyzed phase data. The radar system starts from a flat earth model and gathers height information of the actual terrain as the platform approaches it. Height ambiguities are corrected by removing redundant 2? multiples from the unwrapped phase difference between the echoes.
    Type: Grant
    Filed: March 16, 2015
    Date of Patent: April 3, 2018
    Assignee: Elbit Systems Ltd.
    Inventors: Hans Martin Braun, Gadi Maydan, Holger Baessler, Carston Jonas, Ofer Klein
