A Concept Study of Near-Field Imaging Using Frequency Modulated Continuous Wave Radar

The paper presents a concept for near-field imaging of a scattering device under test using measurements taken by a Frequency Modulated Continuous Wave (FMCW) radar that has linearly increasing frequency with time. A suitable formulation of a near-field transformation for the monostatic FMCW observations is also discussed. A scattering model based on ideal point scatterers and point observations is used to describe the involved steps. Finally, a numerical example is included to demonstrate the imaging performance.
