Applications of α-β and α-β-γ Filtering in Burst Arithmetic Based on Delay-Time

制导引信一体化起爆算法研究的一个重要方面就是通过对最佳起爆延时的估计来确定炸点,而对测量数据进行滤波从而提高炸点的估计精度是其中的一个必要环节。α-β和α-β-γ滤波算法ααα具有计算简单,工程中易于实现的特点。本文针对导引头测距测角模型中基于延时控制的算法,使用c++builder工具进行仿真试验。研究结果表明在基于导引头测距测角模型进行起爆延时的计算中,α-β和α-β-γ滤波是可行的,同时根据仿真讨论了在滤波中影响炸点估计精度的因素及如何合理选取δ因子。

It is essential to estimate delay-time for the burst control model based on the guidance integrated fuze technology,the key step of which is to process the measured information with filter arithmetic for the purpose of improving the estimation of the best burst time.In this paper,α-β and α-β-γ filter arithmetic is discussed based on the burst model controlled by delay-time information under the condition that guider providing distance and azimuth information.The factors that will influence the burst time and how to choose the parameter δ through simulation is also studied.
