ISAR (inverse synthetic aperture radar) signal time-frequency imaging method

The invention provides an ISAR (inverse synthetic aperture radar) signal time-frequency imaging method. The method includes: reconfiguring multiple transient ISAR images by means of NSCT (non-subsampled contourlet transform) during ISAR signal time-frequency imaging to obtain ISAR images. Optimal IS...
