摘要:
以仅能获取角度信息的全捷联导引头为研究对象,针对采用直接微分提取惯性视线角速率时存在的噪声放大问题,基于跟踪微分器设计了一种全捷联制导信息提取算法。结合导引头的性能指标要求,对3种不同形式跟踪微分器的提取效果进行了对比分析。仿真结果表明,采用非线性微分器进行惯性视线角速率提取,可以减小延迟时间,避免噪声放大,有效提高制导精度,具有一定的工程应用价值。

Abstract:
Strapdown seeker has been recently adopted for short-range guided weapon to satisfy the demand for re-ducing the size and cost of guidance and control units.However,the detector of strapdown seeker is fixed rigidly tothe weapon body,and many traditional guidance information processing methods cannot be applied directly,be-cause of the change of detection reference and mode.Due to the weakness of strapdown seeker,inertial line-of-sight(LOS) angle rate extraction in the strapdown seeker is investigated based on the analysis of decoupling weapon atti-tude from the measurement of strapdown seeker.Considering background noise and any inaccurate metrical informa-tion,we introduce tracking-differentiator to obtain more precise inertial LOS angle rate for proportional guidance lawand design guidance system structure of strapdown guidance weapon.The performance of each of three types oftracking-differentiator is discussed according to the characteristics of seeker.Simulation results and their analysisshow preliminarily that the proposed extraction method improves the guidance precision of bomb,thus providingcertain useful information for engineering application.
