Modelling Child Life Presence Detection with Ultra-Wideband Radars for an Automotive Environment

The field of applications for ultra-wideband (UWB) radar has been growing in recent years. One interesting use-case is life presence detection, which is finding living bodies - human or animal - in an otherwise static environment. An example is the localization of humans under debris (e.g. after earthquakes). But also, the automotive sector has found use-cases for UWB radars: monitoring of the driver's vital functions or reminding the driver of children or animals left inside, when the user locks the car and walks away. In particular, it is quite a challenge to detect infants in cars within a short period of time. Compared to adults not a lot of measurement data is available for infants and there are also no appropriate models for numerical simulation. This paper presents the development of such a model including results from simulations that make use of the model.
