海上目标RGPO干扰检测方法仿真研究

针对海面复杂电子对抗环境下单脉冲跟踪雷达所面临的目标距离波门拖引(RGPO)干扰问题,为确定RGPO干扰的存在并对其进行精确时间定位进而采取有效抗干扰措施,需对干扰开展有效的检测.在分析了RGPO干扰和小波检测理论的基础上,结合海上目标所建立的单脉冲雷达跟踪距离函数,利用Daubechies (db)小波进行了RGPO干扰的奇异性检测.仿真结果分析表明,db小波检测的方法可以准确检测出干扰的存在,还能对其进行时间定位,完全可以应用于海上目标RGPO干扰的检测与分析.

Simulation Research on RGPO Jamming Detection Method for Sea Targets

In order to solve the interference problems of target range gate pull off (RGPO) faced by the monopulse tracking radar under the sea complex electronic countermeasure environment,and to determine the existence of RGPO jamming and precisely locate its time and then to take effective anti-jamming measures,effective detection of interference is required.Based on the analysis of RGPO jamming and the theory of wavelet detection,combined with the monopulse radar tracking distance function established by the sea targets,Daubechies wavelet (db) is used to detect the singularity of RGPO jamming.Simulation results show that the db wavelet detection method can accurately detect the interference,also on the time orientation,which can be completely applied to the detection and analysis of RGPO jamming at maritime targets.
