The article provides an analysis of existing noise immunity interrogations surveillance of airspace designed to identify objects on the basis of "the – another" and the implementation of the proposed method of spatial signal processing techniques on the airplane transponder systems under consideration. It is shown that the use of spatial differences interrogators allows us to go from the service request signal to the maintenance of a particular interrogator and this significantly improve the noise immunity of interrogations surveillance systems.
