The Design of the Leaking Signals Cancellation Unit of Radio Fuze based on FTLMS Algorithm

阐述了自适应干扰对消的基本原理 ,并基于自适应投影原理 ,提出一种改进的 FLMS算法—— FTLMS算法来提高收敛速度。着重讨论了 FTLMS算法的原理、实验方法和程序设计。理论分析表明 ,FTLMS算法具有运算量小 ,收敛速度快。并在此基础上设计了一种引信泄漏信号对消器。

In this paper, an improved FLMS algorithm with fast convergence speed-- FTLMS algorithm is proposed, based on the adaptive algorithm, and the theory on adaptive interference cancellation is dealed with detail. Theoretical analysis shows that the FTLMS algorithm has less amount of caculations and fast conergence. Acroding to this theory, an adaptive cancellation unit processing the leaking signals of radio fuze is deviced. The concerned experiment and simulation indicates that the unit is effective.
