The Composite Extended-range Correction Ballistic Parameters Of The Timing Detection Technology

Compared with an ordinary projectile, a hybrid base—bleed—rocketextended—range projectile has longer range, but the precision is lower。The trajectory correctable technology will greatly improve the accuracy ofhybrid base—bleed—rocket extended—range projectile。The trajectorydetection technology, one of the main technologies of trajectory correction,is studiedo In this paper, a type of radar which can only track one targetis used as trajectory detection system。It intends to solve the problem thatis how the radar detects several projectile continually。In order to solve the problem that the radar detects the projectileaccurately, while the gun fires with high speed,the paper emphasizes on fouraspects: First, the reasons why hybrid base—bleed—rocket extended—rangeprojectile has a low accuracy is discussed。Second, reduce the time that theradar needs to search the projectile。Through foretell the projectileerror,radar only searches the special spaceoThus, the time needed will reduce。Third, through using least squares filter method and third order polynomialas, a good result will be obtained by using a few number and the time radarneeds to detect the projectile reduces。Rourth, use the equations of masspoint trajectory to predict the projectile drop point。And compared withthe target point, corrected range will be required。...
