One of challenging trends of enhancement of efficiency of jamming against countermeasures against radar guidance systems of guided missiles (GM) for protection of aerial vehicles (AV) is implementation of adaptive control of their parameters in the closed cycle «jamming signal emission – jamming efficiency monitoring – jamming parameter adjustment – jamming signal emission». Monitoring of jamming efficiency is the key procedure of the cycle and it defines the resulting efficiency of countermeasures against radar guidance systems of guided missiles. Implementation of jamming efficiency monitoring is based on usage of information about the parameters of an electronic battle, the so called monitored parameters.

Objective – substantiation of a rational list and applicability areas of monitored parameters of an electronic combat for the purposes of adaptive control of parameters of jamming against radar homing guidance systems of guided missiles. In order to compass the above goal, two basic tasks are solved: substantiation of the list of probable monitored parameters that meet the above requirements; delimitation of rational applicability areas for the monitored parameters in the progress of an electronic combat.

Methods of system analysis and math modeling were applied to solve the above tasks. In the result of the research conducted, it was established as follows: 1) it is expedient to use the following parameters as basic monitored parameters of an electronic combat for the purposes of monitoring of efficiency of active jamming against radar guidance systems of guided missiles: instantaneous miss value of the attacking missile, difference between the current value of Doppler frequency and its value at the starting moment of jamming generation, amplitude of a radar signal echoed from the attacking missile or their first derivatives; 2) for monitored parameters there exist optimal values of rate of change of controlled jamming parameters; the optimal values provide a practically simultaneous attaining of the extreme value of the monitored parameter and the optimal value of the controlled parameter of jamming; 3) in respect of the minimum width of interval of attaining of the extreme value of the monitored parameter relative to time after which the optimal value of the controlled parameter of the jamming is attained, the rational monitored parameter is the attacking missile instantaneous miss value, which can ensure implementation of adaptive control of jamming parameters within the whole bracket of ranges of jamming generation start.
