基于PRI变换法的脉冲信号分选算法

摘要

脉冲重复间隔是电子对抗中信号分选的关键参数，本文研究的基于PRI变换法的信号分选算法克服了传统直方图统计法的子谐波问题，对脉冲重复间隔具有很高的估计精度，且具有很好的抗抖动性能。仿真分析表明，PRI变换法对固定PRI，抖动PRI具有很好的估计效果。%The pulse repetition interval （PRI） is a key parameter of radar signal de-interleaving in the field of elec-tronic countermeasures. The signal de-interleaving algorithm based on PRI transform overcomes the sub-harmonic problem produced in the histogram statistical method and can estimate the PRI with high precision, and possesses perfect anti - dithering capability. The simulated results indicate that PRI transform algorithm can estimate effect on fixed PRI and dithering PRI.
