ABSTRACT:
A method of interrogation/response in an IFF type Mode 5 communications system comprises at least the following steps: modulating the header of an interrogation message by using an orthogonal or substantially orthogonal function; detecting the modulation function used for the header and determining the algorithm for the decoding of the information contained in the message. The modulation function is a 16-bit Walsh sequence.
