Abstract
In this paper, the joint time-frequency(JTF) analysis techniques were applied to Inverse Synthetic Aperture Radar(ISAR) imaging and motion compensation (MOCOM P), which compensated for the blurring effect in imaging maneuvering targets using traditional RD algorithm. During the implementation of the JTF algorithm, a Gabor-wavelet transform was employed as the JTF tool to obtain a corresponding 3D time-range-Doppler cube. The simulation results showed different time snapshots of moving target, namely target pose in particular instants. Then, ISAR image formed separately by traditional methodology without any compensation and JTF algorithm were compared. The former is highly distorted and its spectrogram demonstrates the severe frequency shifts between the pulses while the latter is very well focused due to the JTF tool used to compensate motion effect and the frequencies of time pulses are well aligned.
