With the use of the state vector expansion method and the Wiener-Kolmogorov method a time-saving algorithm has been synthesized that is meant for filtering the coordinates of a radio frequency radiation source located on an air vehicle in range-difference radio monitoring systems with mobile reception centers with account of statistical characteristics of errors that occur when determining the reception center coordinates. The effectiveness of the above algorithm is due to the minimal expansion of the state vector wherein it includes errors in determination of radio frequency radiation source coordinates and stems from errors in determination of reception center coordinates. The field - of-use restriction for the suggested algorithm is the same correlation interval for errors that occur when determining the reception center coordinates. The findings can be used when analyzing and justifying radio monitoring systems - characteristics.
