The procedure of parametric synthesis of interference radar guidance systems UR in the dynamics of electronic conflict, which is the following cyclic sequence of actions: radiation of the noise signal with some initial, and on subsequent cycles with the changed values of the controlled parameters; the definition of the phase coordinates UR using onboard ID; calculation of the current values of the instantaneous miss UR and its derivatives; change of the controlled parameters of noise exposure in accordance with the used method of extreme control.
Using the mathematical model of the radio-electronic conflict «adaptive complex EW-guided missile with RGS» the following is estab-lished: implementation of the procedure of parametric synthesis of noise based on adaptive control parameter noise provides a final miss is the same as the optimal value of this parameter for the guidance circuit UR (for the case in question the optimal value of the param-eter is 1 and provided with the final miss UR is 200 m); software installation of fixed values of the parameter, different from its optimal value, leads to a decrease in the efficiency of interference in the indicator of the final miss (when changing the parameter in the range of 0.33 … 1, the values of the final miss vary within 100 … 200 m); the time to achieve the optimal value of the parameter taking into account the transition process in the guidance circuit UR significantly depends on the type and parameters of the control law and for the conditions considered does not exceed 3 s.
It is concluded that the implementation of the procedure of parametric synthesis of interference to radar guidance systems UR in the dynamics of electronic conflict allows to parry a priori uncertainty of data on the parameters of the guidance system and provides an increase in the efficiency of interference almost to a potentially achievable level.
