Measurement of a Baby Dummy with a Channel Sounder in an Anechoic Chamber for Child Presence Detection

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 detection of living
objects – 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 regarding
Infants. This paper presents a statistical analysis from measurements with a baby dummy
in an anechoic chamber.
