Radio imaging allows to locate and track passive targets (i.e., not carrying electronic device) moving in an area monitored by a dense network of low-power and battery-operated wireless sensors. The technology is promising for a wide number of applications ranging from intrusion detection to emergency and rescue operations in critical areas. In this paper, a new approach is proposed where both the average and the variance of the fluctuations of the Received Signal Strength (RSS) induced by the target movement over the links are jointly and optimally exploited for sensing the target location.
