基于概率分析法的歼击机导引效能

 基于传统的概率分析法提出一种评估歼击机导引效能的方法。以发现距离作为整个导引阶段的随机变量，提出导引效能指标。将歼击机在水平面内的航向导引分为远距导引与近距导引，分别把导航站引起的导引误差、歼击机对目标的拦截角作为随机变量，分析歼击机进入机载雷达发现区和武器攻击区的情况。通过计算机载雷达的累积发现概率给出发现距离函数。最后以某型歼击机使用中程空空导弹拦截目标为例，计算歼击机向目标的成功导引概率、有效导引距离及有效导引角度，分析主要参数对导引概率的影响规律。该方法可应用于歼击机空战时导引概率的计算。

Fighter's Guidance Effectiveness Based on Probabilistic Method

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.
