This letter presents an improved image-based coherent Doppler tomography (CDT) technique for near-field radar cross-section measurement. The present formulation, developed using the back-projection algorithm, explicitly incorporates the network analyzer calibration in the near-field to far-field transformation. Experimental measurements and computer simulations are presented to validate the improved CDT technique.
