Abstract :
We present a joint time-frequency ISAR algorithm. This algorithm allows the separation of the original ISAR image into two different images: an ISAR image containing only scattering center information, and a frequency-aspect image showing only resonance features associated with the target. We also show, as an example, the application of this technique to the signal backscattered by a target containing a small open cavity
