Emitter geolocation using received signal strength (RSS) has attracted interest due to the possibility of using simple sensors. The idea is to use measurements of received signal power obtained from multiple sensors to estimate the location of an emitter. This paper presents the results of simulation experiments designed to explore the dependence of the geolocation accuracy on the variance of the power estimates and the number of randomly distributed sensors for a non-cooperative transmitter. The results show the number of sensors that are required to achieve a desired level of accuracy for a given variance in the sensor power measurements.
