Abstract

The invention relates to a method for emitting and receiving wave energy serving, in particular, for actively locating targets, during which, on the transmitting side, a transmitting antenna is supplied with an electrical signal and, on the receiving side, the signal emitted by the transmitting antenna is detected in the electrical received signal of a receiving antenna. In order to conceal the transmitted signal in the background noise thereby drastically reducing the probability of the locator revealing itself, the electrical signal is generated with a temporal course having a deterministic-chaotic structure. A structural measure characterizing the deterministic-chaotic structure of the generated electrical signal is used on the receiving side for detecting the signal in the received signal of the receiving antenna.
