Abstract
An asset detection device and method of using a mmWave radar to determine whether a container is mounted to a transport chassis. The reflected signal may include multiple peaks and may be ambiguous. The device may determine if a peak is within a container range and is above a threshold magnitude. If the peak is not the highest peak in the reflected signal the device may disambiguate the signal by filtering it using a stored average no-container signal. If the peak is not the highest peak in the reflected signal the device may disambiguate the signal by determining if the highest peak is due to multipath. In some cases no peaks may be both above the threshold and within the container range, in which case the device determines there is no container present. The device reports container status determinations and reflected signal analysis to a remote server.
