NON-LINEAR PASSIVE MARKER-PARAMETER DIFFUSER Russian patent published in 2008 - IPC G01S13/74 

FIELD: physics, radio.

SUBSTANCE: invention is related to the field of radio location and may be used, in particular, for detection of objects that are located outside visual observance zone. Non-linear passive marker-parameter diffuser is made in the form of antenna loaded for parameter generator, which may be single-circuit, in the form of parameter circuit that consists of inductance and non-linear capacitance and adjusted for half frequency of probing signal, or double-circuit, which consists of non-linear capacitance and two serially connected electric circuits connected parallel to it, which are adjusted at different frequencies, at that sum or difference of these frequencies is equal to frequency of probing signals, and inductances or electric circuits of parameter generator are arranged in the form of close or semi-close resonator.

EFFECT: realisation of higher interference protection and high efficiency of non-linear transformation for application in searching systems of shipwreck victims detection or rejects.
