The problem of time estimation to reach the given accuracy in determining the distance to the radar by two movable direction spaced-finders is studied. Today there are no valid methods of estimation of this time. Two models of time estimation are proposed: through "geometric" factor only and through "geometric" and "accuracy" factors. For each of the models the expressions to estimate required time to achieve given accuracy of determining the distance to the radar and the dispersion of the errors of its estimation are obtained. Common use of "geometric" and "precision" factors in the solution of this problem allows to reduce required time more than for an order. Accuracy of estimated time may be less than one second. Numerical examples are presented, showing the possibility of using this method in the aircraft for prediction time of task solution attribute.
Key words: direction finding, passive location, radar location, triangulation, accuracy, positioning, range, bearing, movable direction spaced-finders.
