Abstract :
The purpose of this paper is to extend the technology of synthetic aperture (SA) imaging used in radar (SAR) and sonar (SAS) to the THz range (SAT). This novel approach in THz will be applied in the domain of non-destructive testing (NDT). The paper presents simulated SAT images which are demonstrating the performance of a synthetic aperture time domain reconstruction processing. The generated SAT target responses of broadband radiation show high resolution and high signal-to-noise ratio (SNR) which lead to an improvement of non-destructive defect identification.
