摘要
在对传统的脉冲重复间隔(PRI)变换法进行介绍的基础上,提出了一种改进型的PRI变换法来估计脉冲重复间隔,并给出了相应的门限设定方法,另外,文中还提出了一种适用的快速脉冲抽取算法。仿真表明,该方法对固定PRI、抖动PRI和参差PRI脉冲序列都有较好的估计效果。
The traditional PRI transform method is presented in this paper firstly. Then a modified PRI transform method to estimate pulse repetition intervals is irttroduced. Moreover, it presents a relevant method to set detection threshold. Furthermore, this paper also brings forward a applicable method to pick up pulses rapidly. According to the simulation results, the modified method can estimate pulse repetition intervals of stable PRIs, jittered PRIs and staggered PRIs efficiently.
