Abstract
The new technique of inverse synthetic aperture radar (ISAR) imaging for object with varied rotation rate is introduced. It is assumed that the polynomial phase signal (PPS) model is appropriate for the radar echo signal, and the radar image could be achieved via the polynomial coefficients. Here, the radar echo signal is modeled as PPS with order three, and the polynomial coefficients are estimated by the improved form of Chirplet decomposition. Numerical results show the correctness for the proposed technique.
