摘　　要：在现代电子战环境中,雷达系统面临着各种复杂的干扰威胁,其中,间歇采样干扰是一种有效的干扰措施,它通过在时间上非连续地发射干扰信号片段来影响雷达的检测和跟踪能力。本文对间歇采样切片干扰的实现进行了详细的理论分析和工程实现验证,通过对切片干扰参数以及干扰时序的控制提出了三种间歇采样切片干扰的实现方式。通过理论分析以及工程实现验证,结果表明,间歇采样切片干扰能够对脉冲压缩体制雷达系统产生有效的干扰效果。该研究为电子战领域提供了一种创新的干扰手段,同时也为雷达系统的抗干扰设计提出了新的挑战。In the modern electronic warfare environment,radar systems are faced with a variety of complex jamming threats,among which intermittent sampling slice jamming is an effective jamming measure,which affects the detection and tracking ability of radar by transmitting discrete jamming signal segments in time.In this paper,the realization of intermittent sampling slice interference is analyzed and verified in detail,and three kinds of intermittent sampling slice interference realiza-tion methods are proposed by controlling the slice interference parameters and interference timing.Through theoretical analysis and engineering verification,the results show that intermittent sam-pling slice jamming can produce effective jamming effect on pulse compression radar system.This research provides an innovative jamming method for the field of electronic warfare,and also pres-ents a new challenge for the anti-jamming design of radar systems.
