1. A method of two-dimensional (2D) velocity estimation of an object located in a first area, the method comprising:

  • determining round trip times (RTTs) of signals from two or more signal sources to the object;

    determining delta RTT values of the signals subsequent to relocation of the object within the first area, based at least in part on the determined RTTs;

    determining angles of arrival (AOAs) of the signals at the object; and

    calculating a 2D velocity estimate based on the delta RTT values and the AOAs.
