The article is devoted to study of influence of changing energy parameter on estimation of accuracy of measuring position parameters of drones by time difference of arrival (TDOA) system through use of spatial-temporal signal processing. In MATLAB modeling of dependences of mean square deviation of radio emission source (RES) position error on signal-to-noise ratio in TDOA system when spatial-temporal signal processing is applied. The description of methodology of building maps of levels of standard deviation of RES position error depending on energy parameter for a system of five receiving points is presented. This approach can be useful in design of TDOA system with spatial-temporal signal processing, since it allows predicting errors received in coverage area. The distinctive feature of technique is that standard deviation of difference-distance measurement depends on mutual location of RES and receiving points.
