Abstract:

It is importance tache of the early warning aircraft’s battle effectiveness that to steer fighter in long distance. In order to quantitatively analyze and evaluate the longdistance guidance effectiveness, longdistance guidance successful probability is given as the index for effectiveness. Firstly, the course of longdistance guidance is divided into horizontal and vertical guidance, and the error analysis models of the horizontal guidance and the vertical guidance are built up according to parallel approach guidance rule. Secondly, according on root mean square error of the course is derived, the root mean square error of elevation is also obtained through derivation, meanwhile long distance guidance model is built up based on probability analyze method. Finally, an example of a fighter intercepting a target by the early warning aircraft’s longdistance guidance is given to analyze effect rules of primary parameters on long distance guidance probability, including target intercept distance, target parameters measure precision, intercept speed and antenna scan area. Simulation results prove the effectiveness of the proposed model.
