Abstract

Exemplary embodiments of the present invention provide a method for determining the design of an ultra-wideband sensor for a vehicle. The method comprises obtaining information about the link budget for the ultra-wideband sensor and obtaining information about the path loss of a signal emitted by the ultra-wideband sensor. Furthermore, the method comprises obtaining information about the minimum link budget required to detect an object and determining whether the design of the ultra-wideband sensor is sufficient for detecting the object. The determination of whether the design is sufficient is performed based on the link budget, the path loss, and the required minimum link budget. If the design of the ultra-wideband sensor is insufficient, the method further comprises adjusting the design of the ultra-wideband sensor to detect the object.
