Abstract
A method for generating an image may include translating a radar system about a target area at a selected angular rate and at a predetermined radius from the target area and transmitting a plurality of radar signals in a predetermined frequency range from the radar system as the radar system is translated about the target area. The method may also include collecting a plurality of backscattered radar signals from the target area resulting from the plurality of transmitted radar signals and forming a plurality of Doppler-based projections from the plurality of backscattered radar signals. The method may further include generating an image of the target area using radar tomography and the Doppler-based projections.
Claims20
A method for generating an image, comprising:
- translating a radar system about a target area at a selected angular rate and at a predetermined radius from the target area;
- transmitting a plurality of radar signals in a predetermined frequency range from the radar system as the radar system is translated about the target area;
- collecting a plurality of backscattered radar signals from the target area resulting from the plurality of transmitted radar signals;
- forming a plurality of Doppler-based projections from the plurality of backscattered radar signals;
- and
- generating an image of the target area using radar tomography and the Doppler-based projections.
A system for generating an image, comprising:
- a radar system mountable to a vehicle for translating the radar system about a target area at a selected angular rate and at a predetermined radius from the target area;
- an antenna associated with the radar system that transmits a plurality of radar signals in a predetermined frequency range from the radar system as the radar system is translated about the target area;
- a collection aperture that collects a plurality of backscattered radar signals from the target area resulting from the plurality of transmitted radar signals;
- and
- a processor adapted to form a plurality of Doppler-based projections from the plurality of backscattered radar signals and to generate an image of the target area using radar tomography and the Doppler-based projections.
A computer program product for generating an image, the computer program product comprising:
- a non-transitory computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising:
- computer readable program code configured to cause a radar system to transmit a plurality of radar signals in a predetermined frequency range from the radar system as the radar system is translated about a target area;
- computer readable program code configured to cause the radar system to collect a plurality of backscattered radar signals from the target area resulting from the plurality of transmitted radar signals;
- computer readable program code configured to form a plurality of Doppler-based projections from the plurality of backscattered radar signals;
- and
- computer readable program code configured to generate an image of the target area using radar tomography and the Doppler-based projections.
