Abstract
A method is disclosed for searching and locating a target device emitting a wireless signal. The signal strength of the wireless signal is detectable and measurable. The method comprises defining a distribution of the signal strength within the search area, on the basis of an initial condition, then iteratively performing steps of interrogating the distribution to determine a plurality of inquiry locations, determining signal strength at those inquiry locations, and updating the distribution on the basis of the determined signal strengths. Iteration continues until a convergence condition is reached, whereby inquiry locations become proximate within a threshold.
