With use of a method of the interfaced systems the analytical technique of optimization of algorithm of interference control is developed by leading to interruption of control of homing system at the expense of a temporary exception of possibility of measurement of coordinates of the target. Optimization of algorithm of interference control consists in determination of values of time and duration of influence of hindrances at which the maximum probability of missing is reached. The technique is developed taking into account speed of algorithm and possibility of group prompting of objects on the target. Parametrical optimization of algorithm of interference control characterized by existence and absence of effect of post-action is carried out, at single impact on homing systems with the interfaced pulse characteristic of the fourth order. Extreme character of an optimized indicator of efficiency of the algorithm, caused by resonant properties of system of homing is established. It is shown that the interference leading to interruption of control and post-actions not possessing effect in the conditions of the set temporary restrictions are effective at simultaneous prompting 1...2 objects on the target. Hindrances with effect of post-action allow to provide high probability of missing in case of simultaneous prompting to 4 objects on the target, optimum duration of their influence can make 0,5...1,6 s. The received dependences illustrate possibility of a choice of optimum time of switching of a interference of missing providing the maximum probability. For effective application of algorithm of interference control in the conditions of group prompting of objects it is necessary in 1,5 times and more to reduce errors of definition of time of prompting of object on the target.
