Principle and algorithm of inverse synthetic aperture radar imaging for maneuvering targets

Inverse synthetic aperture radar imaging of the non-cooperative maneuvering target is a challenging task due to its time-varying orientation and rotation velocity which denies accurate measuring. The general principles of this imaging were described and an algorithm was proposed for its application in the situations that the maneuverability is not too serious and the Doppler variation of sub-echo from scatterer can be approximated as a first order polynomial. The imaging results using real data show that the algorithm is feasible.
