Abstract:

In view of the range optical measurement equipment in the remote high-speed projectile target tracking problem existing in the measurement process,the movement characteristics of target of the projectile and the infrared radiation characteristics are analyzed,by using the computer simulation curve and surface of flying projectile flight trajectory with time,get under the condition of a given target radiation changing with time curve,obtained meet the demand of tracking measurement range projectile target features.Through the simulation measurement and hardware-in-the-loop simulation measurement of the shooting range it is applied to the special test so the shooting range.It plays an important role in the formulation of projectile measurement scheme and the evaluation of equipment tracking performance,and improves the success rate of tracking measurement.The research results can be extended to the tracking measurement of other types of targets and have good practical value.
