Abstract:

A method of evaluating fighter’s guidance effectiveness was given based on conventional probability analysis method. Indexes of guidance effectiveness were given by treating the detection distance as a random variable in whole guidance stage. The fighter’s level direction guidance was divided into longdistance guidance and shortdistance guidance. To analyse the situation that the fighter enters into the detection region of the airborne radar and the attack region of the weapen, the guidance error from guidance station was treated as a random variable. When the target is in the attack region of the weapon,the interception angle of fighter against target was regarded as a random variable.The function of the detection distance was given by calculating cumulative detection probability of the airborne radar.An example of a fighter intercepting a target using middle-distance air-to-air missile was given to calculate the successful guidance probability of fighter to target,the effective guidance distance and angle,to analyse rules of primary parameter's effect on guidance probability.The method can be used to solve the problem of guidance effectiveness of fighter in air battle.
