This contribution addresses the determination of the radar channel when operating in the near field of electrically large targets, which is a common scenario in modern short-range radar applications such as vital-sign sensing. With the focus on computational simplicity and the inclusion of near-field scattering phenomena, the proposed approach combines physical optics (PO) concepts and the far-field radiation pattern of the radar antenna to determine both amplitude and phase of the receive signal. The numerical implementation relies on basic scalar evaluations. The agreement between the simulated and measured radar channel of a metallized human-body-shaped object at 24 GHz and 61 GHz proves the effectiveness of the approach.
