摘要
随着导弹技术的不断发展,导弹末段制导中的比例导引律成为人们研究的重点.比例导引律实现简单,其通过调整导弹与目标之间的角速率就能达到制导的目的.但是比例导引律在设计的时候往往将导弹和目标看成质点,忽略了大气阻力等客观因素,这使得制导的精度并不高,以比例导引为基础,用最小脱靶量为设计原则,辅以直接侧向力从而提高制导精度.通过仿真表明以直接侧向力控制发动机可以很好的完成导弹对目标的打击.
Abstract
With the development of missile technology, proportional navigation guidance law has become more and more important in Terminal guidance. It is easy to realize proportional navigation guidance law by adjusting the missile and the target angular rate. But proportional navigation guidance law take the missile and target as a particle.and Ignoring the air drag or other objective factors, so proportional navigation guidance law not always accurate. In order to improve the precision of guidance and control, The article put forward direct lateral force that based on the proportional navigation guidance and Using the minimum miss distance for the design principles. Finally,The simulation results show that the direct lateral force could complete missile strike against targets.
