System and method for implementing personal emergency response system based on UWB interferometer

A non-wearable monitoring system comprising:

• a radio frequency (RF) interferometer configured to transmit signals at a specified area and receive echo signals via an antenna array;
• an environmental clutter cancelation module configured to filter out static non-human related echo signals;
• a human state feature extractor configured to extract from the filtered echo signals, a quantified representation of position postures, movements, motions and breathing of at least one human located within the specified area;
• a human state classifier configured to identify a most probable fit of human current state that represents an actual human instantaneous, wherein the extracted features are vector quantized, and wherein the classifier is configured to find a best match to a codebook which represents the current state being a set of human instantaneous condition/situation which is based on said quantized feature status;
• and
• an abnormality situation pattern recognition module configured to apply a pattern recognition based decision function to an identified states patterns and determine whether an abnormal physical event has occurred to the at least one human in the specified area.
