  • The radar echo separation of appendix part is the key for improving ISAR image of ballistic target. This paper establishes the echo model of ballistic target. And the Doppler difference of body and appendix part is analyzed. A new decomposition in slow-time domain is proposed. The body echo is decomposed into several LFM signal components. The echo of body and appendix is reconstructed. Explicit procedure is given. Simulation result shows that the ISAR image is much better compared to the image based on original data.
