First Claim
1. A method of determining a location of a remote object, comprising:
- transmitting, from a transmitter at a transmitter location on a frame, a transmission signal;
receiving, at a first receiver, a second receiver, a third receiver, and a fourth receiver respectively a first reflected signal, a second reflected signal, a third reflected signal, and a fourth reflected signal, wherein each of the first, second, third, and fourth reflected signals are reflections of the transmission signal off the remote object, and wherein the first, second, third, and fourth receivers are disposed on the frame separated from one another respectively at a first receiver location, a second receiver location, a third receiver location, and a fourth receiver location on the frame;
determining times at which the first, second, third, and fourth reflected signals are received respectively by the first, second, third, and fourth receivers; and
determining, in a processor, the remote object'"'"'s location based on the determined times at which the first, second, third, and fourth reflected signals were received respectively at the first, second, third, and fourth receivers and known locations of the first, second, third, and fourth receivers.

Abstract
Methods and devices of various embodiments enable determining a location of a remote object using radio frequency signal transmitted from a transmitter on a frame and received at four receivers located at separate locations on the frame. First, second, third, and fourth reflected signals from a remote object may be received at first, second, third, and fourth receivers respectively. Times at which the first, second, third, and fourth reflected signals are received respectively by the first, second, third, and fourth receivers may be determined. The remote object'"'"'s location may be determined based on the determined times at which the first, second, third, and fourth reflected signals were received respectively and the locations on the frame of the first, second, third, and fourth receivers.
