摘要
在弹目交会期间引信需要预测剩余飞行时间。采用线性调频Z变换算法(CZT)细化多普勒频率,降低弹目交会期间引信剩余飞行时间预测偏差。采用了多点迭代再对结果求均值的方法,降低了单次测量误差。仿真和模拟器实测试验表明,大脱靶量情况下CZT方法能够提高估计精度。
During the missile-target terminal encounter, fuze need to predict time to go until miss point. This paper attempts to use chirp z-transform algorithm(CZT) refined the Doppler frequency, thereby reducing the predicted error. To reduce the measurement points and single measurement error, using multipoint iterative methods and averaging the results. Simulation and emulator measurement shows that the CZT can improve prediction accuracy on large miss distance.
