Abstract
For synthetic aperture radar (SAR) processing, a SAR receives a plurality of SAR signals. The SAR generates a piecewise approximation of the plurality of SAR signals over a coherent processing interval. The piecewise approximation may mitigate phase reflection components of each SAR signal. The SAR further generates an estimate of the scene from the piecewise approximation.
Claims20
A method for synthetic aperture radar (SAR) processing comprising:
- receiving, by use of a processor, a plurality of SAR signals;
- generating a piecewise approximation of the plurality of SAR signals over a coherent processing interval, wherein the piecewise approximation mitigates phase reflection components of each SAR signal;
- and
- generating an estimate of a scene from the piecewise approximation.
A program product comprising a computer readable storage medium that stores code executable by a processor, the executable code comprising code to perform:
- receiving a plurality of SAR signals;
- generating a piecewise approximation of the plurality of SAR signals over a coherent processing interval, wherein the piecewise approximation mitigates phase reflection components of each SAR signal;
- and
- generating an estimate of a scene from the piecewise approximation.
An apparatus comprising:
- a processor;
- a memory that stores code executable by the processor, the code comprising:
- code that receives a plurality of SAR signals;
- code that generates a piecewise approximation of the plurality of SAR signals over a coherent processing interval, wherein the piecewise approximation mitigates phase reflection components of each SAR signal;
- and
- code that generates an estimate of a scene from the piecewise approximation.
