DETECTION METHOD OF TARGET ROUTE AND FALSE ROUTE FORMED WITH SYNCHRONOUS REPEATER JAMMING (VERSIONS)

摘要

FIELD: radio engineering, communication.;SUBSTANCE: in a detection method of a target route and a false route formed with synchronous repeater jamming in space between its jammer and radar station (RS), which is based on wobbling of a repetition period of sounding signals, there set at wobbling are two strobes: one for signals of the expected false route and the other one for signals of the expected target route; a decision is taken on the route being checked depending on a strobe in which a signal has been received, and if the signal has been received in both strobes, a decision is taken on the fact that it is a target route protected by a false route. The achieved technical result as per the second version - detection of a false route and a target route at occasional use of variation of RS signal parameters. The above result is achieved by the fact that in the detection method of the target route and the false route formed with synchronous repeater jamming in space between its jammers and RS, based on variation of parameters of sounding signals at neighbouring sounding intervals, there preserved is a possibility of receiving signals of the preceding sounding interval, and a decision is taken on the route being checked: a false route if there has been received a signal with parameters of the preceding sounding interval; a target route if there has been received a signal with parameters of the current sounding interval; a target route protected by a false route if there have been received signals with parameters of the preceding and the current sounding intervals.;EFFECT: avoiding overload of devices at detection of target routes and false routes.;2 cl
