Paper Title:
A New ISAR Imaging Method of Ballistic Midcourse Target
  Abstract

A new micro-motion ISAR imaging algorithm based on the MP sparse decomposition is proposed in this paper. The algorithm use the changes of azimuth angle caused by micro-motion to achieve high cross range resolution, and decompose the echoes of the same range cell before Wigner-Ville transformation to eliminate the cross-term interference. Compared with the traditional Range-Doppler algorithm and the Wigner-Ville imaging algorithm, the new algorithm considered here exhibits better imaging precision and is without cross-term interference. The simulated results have demonstrated that it is an effective method for the micro-motion target imaging.
