Application of the reassignment of time-frequency distributions to Doppler radar tomography imaging of a rotating multi-point object

Radar tomography allows to build a two-dimensional image from one-dimensional functions obtained from radar returns. In this paper the possibility of usage of the reassigned spectrogram as well as different reassigned forms of time frequency distributions in the Doppler radar tomography imaging is evaluated. The image is obtained from a multi component signal with time-frequency modulations resulting from rotation. The algorithm of imaging with high resolution is tested on simulated data.
