Abstract

The present disclosure is directed to motion detection and recognition using segmented data from reflections of transmitted signals. An apparatus includes a transmitter, a receiver, and a processor. The processor may cause the transmitter to transmit pulses of an RF signal, the reflections of which are received by a receiver. For each of a number of consecutive segments, the transmitter may transmit N pulses of the RF signal, followed by quiet period. The processor may determine amplitude and phase data for reflections received by the receiver. Over a number of consecutive segments, the processor may detect and classify the amplitude and phase data change over time.
