A pseudo-noise-modulated spread spectrum is irradiated undirectedly--or, encoded by different modulation, into mutually displaced spatial sectors--and the energy (20) received after reflection at a potential target (13) is cross-correlated, using the pseudo-noise code which is predetermined at the transmission end, in order to provide a spherical monitoring effect which is continuous but which cannot be located in respect of its origin, to provide a warning in particular for marine craft, land vehicles and aircraft against an attacking guided missile as ...
[ What is claimed is:] [1.] A method of initiation a wake-up sensor with a radar detector while preventing self-betrayal for activating a target tracker in response to the sending by said radar detector of the approach of an attacking missile to an armored land vehicle or marine craft, comprising radiating from a transmitter of the radar detector a reduced-energy carrier so as to be nondirectedly propagated in continuous-wave operation into surrounding space into mutually adjacent spatial sectors over a large frequency spectrum and effecting modulation t...
