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 7):
The method for terahertz ISAR imaging of  claim 1 , wherein in the discretizing the first target function F(k x ,k y ) to obtain F(k xmn ,k ymn ), and interpolating on the k xmn  domain, the interpolating is performed through a Stolt interpolation method satisfying F \ue8a0 ( k x , k ymn ) = \u2211 n \ue89e J m \ue8a0 ( n \ue89e \ue89e \u0394 \u03c9 ) \ue89e F \ue8a0 ( n \ue89e \ue89e \u0394 k x , k ymn ) \ue89e h \ue8a0 ( k x - n \ue89e \ue89e \u0394 k x ) wherein h \ue8a0 ( k x ) = sin \ue89e \ue89e c \ue8a0 ( k x \u0394 k x ) , J m \ue8a0 ( \u03c9 ) = 4 \ue89e \ue89e k c \ue89e 4 \ue89e \ue89e k 2 + k um 2 .
