Experimental research on vehicle‐borne SAR imaging with THz radar

Vehicle-borne SAR is one of the most important applications of radar systems, playing a more and more major role in civilian and military fields. Vehicle-borne SAR imaging experiments with a 0.22-THz radar system are introduced in this letter and the imaging processing based on practical problems is presented. High quality imaging results are obtained after a series of processing such as optimum parameters estimation, harmonic interference correction and vibration compensation. Finally, analyses of the imaging results verify the validity of the imaging processing, which provide support to the practical application of terahertz vehicle-borne SAR imaging systems.
