ABSTRACT:
A method for identifying radar targets, especially ships at sea involves transmitting a first interrogation pulse, thereby causing a responder to generate a first identification signal containing a first set of data concerning the identity of the target, transmitting a second interrogation pulse causing the responder to generate a second identification signal containing a second set of data concerning the identity of the target and thereafter combining the two sets of data. The method reduces bandwidth requirements and garbling. An interrogator and responder for use in the method are also provided.
