1. 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 cancellation 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 status; and an abnormality situation pattern recognition module configured to apply a pattern recognition based decision function to the identified states patterns and determine whether an abnormal physical event has occurred to the at least one human in the specified area.
