【摘要】 本文是“十五”某国防预研项目的重要组成部分，对装甲目标及其在隐身材料下的散射特性和辐射特性测试方法进行了研究，为相关国防项目的研究提供依据。 本文首先通过对毫米波波段目标散射特性的测试原理的分析，确定了毫米波散射特性测试方法及隐身效果的评估方法；对远场条件、测试背景在雷达测试中的影响及衰减给出理论和实践上的分析；对雷达测试中的重要方法-缩比测试建立了较为清晰的数学模型。 其次，进行了3mm脉冲雷达的改进，对改进结果进行了实测对比与校验标定工作，对装甲目标进行了外场测试和结果的分析。 再次，对毫米波波段目标辐射特性的测试原理，进行了理论基础、地物背景和立体金属目标方面的阐述和论证。 最后，本文开展了毫米波辐射计的测试原理与测试方法的分析和论证工作，并进行了实际地物背景的毫米波辐射特性的对比测试与数据分析工作，提出毫米波波段金属目标辐射特性控制的初步方案。 全文的工作旨在为相关的国防科研提供理论和实践上的依据。更多还原

【Abstract】 This paper is an important part of a Native Defense preparatory study task in the Ten-five-year plan. Measurement methods of scattering and radiation characteristic of army-targets are systematically researched so as to provide basis for the related Native Defense Project.Through the analysis for the MMW band target’ s test principle of scattering characterstic to first, maked sure the test method for scattering characteristic and the valuation method for concealed results;gave the far -field term and test background in radar test of influence and attenuation with theories and practice analysis ;established clear mathematics model for the important radar testing method contraction test.The next in order, proceeded the improvement of a pulse MMW radar, carried out this improvement’ s practice measuring contrasts , verify and demarcate work, proceeded the outfield test and result’ s analysis to the armor target .Again, carried through the base of theory, terra background and solid metal target’ s expound and demonstrate for MMW band target’ s radiation characteristic.Finally, this text putted up the analysis of test principle and test method for MMW radiometer, processed pratical terra contrast test and data’ s analysis for radiation characteristic, putted forward the primary scheme for MMW band metal target radiate characteristic’ s control.The aim of full text is providing the academic and pratical proof for related national defense scientific researching.更多还原
