摘　　要：时分法多目标干扰是为了缓解现代电子战中目标数多而干扰资源不足的矛盾所采取的措施。通常认为,时分法多目标干扰的优点是功率容量可达到100%,能使功放工作于高效率的丙类工作状态。通过对时分法多目标干扰的话音可懂度、中断次数、干扰占空比及功率利用率和频谱分布等特性相互关系的分析和模拟,提出了其功率利用率是随干扰目标数以及欲达到的话音可懂度指标而变化这一观点,阐述了时分法多目标干扰的应用范围和存在的局限性,为电子干扰技术手段提供借鉴。Time - sharing multi - target jamming is a measure for relieving the contradiction between too many targets and less jamming resource in modern EW. General thinking, time - sharing multi - target jamming has the superiority that its power capacity can reach 100 percent, which makes power amplifier work efficiently at C type. This paper puts forward the opinion that power efficiency changes with the number of jamming targets and speech articulation by means of discussing the interrelation among speech articulation, interrupt time, duty ratio of jamming, power utility efficiency and spectral characteristic. It also discusses the usage range and limitation of the method, which provides a reference for EW technical measures.
