摘要：

目标的电磁散射特性对回波信号的特性影响巨大。以连续波多普勒体制无线电引信为依托，以平板目标为主要研究对象，研究体目标效应影响下的多普勒信号特性。采用物理光学法和物理绕射法计算目标表面和边缘的雷达散射截面积。建立了平板目标特性模型，结合引信空中弹目交会模型，探讨弹目交会过程中多普勒信号幅度和多普勒频率的变化规律。

Abstract:

A fuzespecific method of analyzing the target electromagnetic scattering properties is presented. The continuous wave Doppler fuze model is used, and the research is mainly about the platetargets. The main purpose is to provide the engagement echo signal characteristics, including amplitude and frequency characteristics on the condition of the near field. The methods of physical optical (PO) and physical theory of diffraction (PTD) are used to calculate the radar cross section (RCS) of target surfaces and edges. Based on the air engagement model, the model of platetarget scattering is built, and the changing law of Doppler amplitude and frequency in the near field is provided.
