摘要：

Although the classic radar equation has been widely used to analyze the link budget of an automotive radar, it is valid only when the targets are located in the far -field region of the transmitted field and the receiving antenna is located in the far -field region of the scattered field. This paper confirms this hypothesis using measured and simulated data for short-range radars. Furthermore, a novel radar equation based on the Fresnel diffraction formula is proposed for application in situations where the receiving antenna is located in the radiative near -field region (or Fresnel region) of a target, but the target is situated in the far -field region of the transmitting antenna. In addition, the proposed radar equation is assessed by comparing the measured and simulated data.
