基于脉冲串的雷达信号分选性能评估指标

针对目前基于脉冲的雷达信号分选性能评估指标不够全面且战术性体现不足的问题，本文将分选过程置于电子侦察流程中进行考察，基于去交错结果提炼出更契合战术性的分选性能评估指标。在评估分选性能时，以脉冲串为处理单元，重点关注辐射源的漏检和脉冲串的虚警。此外，考察了分选出子谐波的情况和分选处理流程的时间，又从电子情报质量的角度考察了脉冲重复间隔（Pulse Repetition Interval,PRI）估计和脉冲序列匹配度。仿真实验研究了PRI抖动和脉冲丢失对分选性能评估指标的影响。仿真结果表明，所提评估指标的实验数据与PRI抖动和脉冲丢失率对分选过程的影响机理相互印证，体现了所提指标的合理性。此外，借助评估指标可以对分选过程进行精准分析，所提评估指标的有效性及全面性得到验证。

Performance Evaluation Index of Radar Signal Sorting Based on Pulse Train

? ?Aiming at the problem that the performance evaluation index of radar signal sorting based on the pulse is not comprehensive and the tactical performance was not enough， this paper put forward the performance evaluation index based on the pulse train to evaluate the sorting performance. Analyzing the sorting process from the perspective of the electronic reconnaissance， this paper extracted the more tactical evaluation index based on the de-interleaving result. With a pulse train as a processing unit， the proposed indexes focused on the missed detection of radiation source and false alarm of pulse train when evaluating sorting performance. In addition， the situation that sub-harmonics appear in the sorting results and the time required in sorting process were investigated， and the Pulse Repetition Interval （PRI） estimation and pulse train matching degree were also investigated from the perspective of electronic information quality. The effects of PRI jitter and pulse missing on the evaluation indexes were studied in simulation experiments. The simulation results show that the experimental data of the evaluation indexes were mutually verified with the influence mechanism of PRI jitter and pulse loss rate on the sorting process. The rationality of the proposed indexes is fully reflected. With the help of the proposed evaluation indexes， researchers can accurately analyze the sorting process. The validity and comprehensiveness of the proposed indexes are fully verified.
