1. A system for localizing an object, comprising:
a radio transmitter disposed in a first location;
a radio receiver disposed in a second location;
a processor operatively coupled to the radio transmitter and to the radio receiver;
and a memory operatively coupled to the processor,
the memory comprising instructions stored thereon that, when executed by the processor, cause the processor to:
send a first command to the radio transmitter to transmit a continuous radio wave;
send a second command to the radio receiver to receive a reflected radio wave;
receive from the radio receiver a signal indicating the reflected radio wave is within a spatial region of interest;
and determining a three-dimensional location of the object within the spatial region of interest based on the reflected radio wave,
wherein the instructions, when executed by the processor, further cause the processor to:
identify power peaks within the spatial region of interest using the reflected radio wave,
wherein a peak power amplitude indicates a possible angular location of the object;
estimate an angular location of the object based at least in part on the peak power amplitudes, the first location, and the second location;
and determine the three-dimensional location based on the estimated angular location.
