Abstract:
The disclosure relates to a method and a system for terahertz ISAR imaging. In the method, a chirp signal is transmitted to an imaging target moving at a preset speed and a terahertz ISAR echo signal is received. The terahertz ISAR echo signal is matched filtered in a fast time domain, baseband transformed in a slow time domain, corrected to eliminate a time domain zero offset, baseband transformed, discretized, interpolated, and two-dimensional inverse Fourier transformed to obtain a two-dimensional image of the imaging target.

Claim (Index 4):
The method for terahertz ISAR imaging of  claim 1 , wherein the performing the baseband transformation on the data matrix S M (\u03c9,u) to obtain the baseband transformed data matrix S b (\u03c9,u) and corresponding signal spectrum S b (\u03c9,k u ) comprises:\n performing a Fourier transformation in the slow time domain on the baseband transformed data matrix S b  (\u03c9,u) to obtain the signal spectrum S b (\u03c9,k u ).
