Claim:
1. A method comprising: obtaining, from a first sensing device, first information corresponding to a radio signal received at the first sensing device from a candidate location; obtaining, from a second sensing device, second information corresponding to a radio signal received at the second sensing device from the candidate location; determining that a clock corresponding to the first sensing device is synchronized with a clock corresponding to the second sensing device; determining a first relationship between the first sensing device and the candidate location and a second relationship between the second sensing device and the candidate location; obtaining a first inverse of the first relationship and a second inverse of the second relationship; determining a first estimate of the radio signal received at the first sensing device from the candidate location based on the first information and the first inverse, and a second estimate of the radio signal received at the second sensing device from the candidate location based on the second information and the second inverse; and conditioned on determining that the clock corresponding to the first sensing device is synchronized with the clock corresponding to the second sensing device, measuring an energy emitted from the candidate location based on the first estimate and the second estimate.
