NOVEL ALGORITHMS TO IMPROVE THE PRECISION OF TRACKING FOR IR/MMW COMBINED SEEKER BASED ON DATA FUSION

制导精度是衡量寻的制导武器性能的一项重要指标。导引头对目标的跟踪精度是制约制导精度的主要因素之一。影响导引头跟踪精度的主要因素是IR/MMW误差测量元件的精度。本文从误差测量环节入手 ,基于IR/MMW双模结构 ,采用信息融合处理技术提高其估计精度 ,最终达到降低制导误差 ,提高武器性能之目的。

Guidance precision is a significant performance index for homing guidance weapons. The seeker tracking precision , which is determined by accuracy of measurement of the error measurement component, is one of the major factors that influence the guidance precision. Based on IR/MMW dual mode, common aperture structure and information fusion technology, two approaches are provided to improve the LOS(Line of sight) angular rate estimated precision and finally enhance the weapons performance. Simulation results show that the approaches are effective.
