Method and apparatus for segmented motion sensing

Abstract

A Doppler sensing system includes, in part, at least one transmit antenna, a processor configured to cause the transmit antenna to transmit signals during M repeating cycles of a sequence, and a receiver configured to receive reflections of the signals generated by the transmit antenna. For each cycle, the transmit antenna is set to N different transmit settings each during a different one of N time periods to generate N different signals. The sequence may be uniform or non-uniform. The N time periods may be substantially similar. The transmitter may be set at least twice to at least one of the N settings during each cycle. The receiver optionally includes, in part, a first frequency downconverter adapted to generate in-phase (I) signals and a second frequency downconverter adapted to generate quadrature-phase (Q) signals. The processor generates the I and Q signals from the signals the processor receives from the receiver.
