Abstract
A virtual secondary surveillance radar (SSR) is provided at any desired location within the coverage area of an actual SSR by receiving the interrogations from the actual SSR and the transponder replies thereto. The received signals are processed to yield information as to the positions of the transponders with respect to the desired location, simulating the performance of an actual SSR at that location.
