摘要
针对雷达PRI调制样式识别难题,在分析雷达PRI类型的基础上,提出了能够有效描述雷达PRI调制特征的五种分类特征参数,分析了对存在丢失和虚假脉冲的处理方法,并据此提出了PRI调制样式的识别算法与实现流程,实现了五种典型PRI调制样式的有效识别。理论分析与计算机仿真结果表明,该方法在PRI测量精度较低和丢失虚假脉冲比例较高的情况下具有稳健的识别性能。
Aiming at the shortcoming of the modulation type recognition of radar PRI,five classsified parameters which can effectively describe the modulation characteristics of radar PRI are given based on the analysis of radar PRI types,and the management methods for the missing and spurious pulsesv are analyzed.On these grounds,the recognition arithmetic and realized process for the modulation types of radar PRI are put forword and be used to effectively recognize five representative PRI modulation types.Theoretic analysis and computer simulation indicate that this method is robust in the presence of a low PRI measurement precision and a high rate of missing and spuriou pulses.
