Radar is an attractive technology for long term monitoring of human movement as it operates remotely, can be placed behind walls and is able to monitor a large area depending on its operating parameters. A radar signal reflected off a moving person carries rich information on his or her activity pattern in the form of a set of Doppler frequency components produced by the specific combination of limbs...
Human activity quantification consists of computing a numerical or qualitative metric that indicates the amount of movement a person engaged in a given time interval. Such a metric has important applications in elderly care, wellness and healthcare given the strong empirical relation between a person's health and his or her activity level. This paper proposes and evaluates methods to quantify the...
As radar and communication systems both are RF systems, a combination of both may be possible. The communication channel between transmitter and receiver is modeled and then adapted to include a rotating narrowbeam antenna, common to radar systems, located at the transmitter side. Assuming an omnidirectional antenna at the receiving station, this channel model can help to understand the similarities,...
