Study Of The Target Acquisition Probability Of Composite Guided Middle/Long Range Air-to-Air Missile

In this paper,set the composite guided middle/long range air-to-air missile as the research object,aiming at the problem of target acquisition probability in the shift time,research by modeling and simulation,Monte Carlo method.The main research contents include:Analyze single fighter and dual-fighter cooperative guidance errors in the process of the guidance;Establish the simulation model of the acquisition probability,including the definition of common coordinate system and angle parameters,the relationship between the coordinate system conversion,motion equation;Study the influence of guidance error,the seeker characteristics(range,angle of view,search mode),aircraft and missile and target motion and guidance form(the inertial/satellite navigation,relative angle)on the acquisition probability in single fighter guidance;On the dual-fighter cooperative guidance,study the influence of attitude and position error,relative position relationship on probability analysis;Calculate and analyze the interception probability under typical operation mode.Through the research,get a series of important conclusions of composite guided middle/long-range air-to-air missile acquisition probability,mainly includes:The fighter radar angle error impacts the interception probability most seriously of the guidance error,should focus on improving this error;The bigger seeker distance and angle of view are,the higher acquisition probability is,the proper search mode can significantly improve the acquisition probability;Acquisition probability is directly related to the relative position of the fighter and the target in the shift time,fighter should be as close to the target under the premise ensuring the safety;Compared to the inertial navigation,inertial/satellite navigation and relative angle measurement guidance can improve the acquisition probability,the inertial/satellite navigation is mainly to improve the measurement error of missile position,when the target position measurement error is larger,the relative angle measurement guidance is better in improving the acquisition probability.This study provides an important theoretical basis for the improvement of the acquisition probability of the composite guided medium/long range air-to-air missile and the operational capability.
