引信应对的近场目标一般具有扩展目标的特性, 扩展目标存在的起伏特性是引信设计要考虑的重要方面, 现就扩展目标起伏的机理和应对措施进行了初步讨论。首先综述了引信目标回波起伏的诸多原因, 并分析指出了扩展目标存在相关起伏的必然性, 然后探讨了引信设计时应对目标起伏的方法措施, 进行了仿真和试验, 结果表明了应对目标起伏的方法的有效性。

The near-field target of fuze has commonly extended characters. The fluctuation characters of extended target should be considered deliberately when designing a fuze. In this paper, the theory of fluctuation and the methods to cope with the fluctuation are discussed primarily. At first, several reasons of the fluctuation are introduced. Analysis shows that the extended target has inevitably the fluctuation characters. Next, the design methods to cope with the fluctuation are discussed; simulation and experiment are conducted. The result proves the validity of design methods to cope with the fluctuation.
