A method for target detection friend - enemy and arrangement for carrying out the method

摘要

The invention relates to a system for target detection friend - enemy, which in the millimeter wave range - by means of a interrogators as well as of a transponder is operated, wherein the interrogator and transponder essentially the same electronic units and substantially at the same central transmitter - and receiving frequency, wherein between these a large frequency difference is tolerable. In this case, the reaction of the interrogator, to a transmitting / receiving - directional antenna, while the transponder has a transmitting / receiving - round antenna has.
