48826 最后,通过仿真实验证明了改进的超综合孔径系统的性能相比于原始超综合孔径系统有很大的提高,主要表现在:一是天线阵列方面,阵列因子的旁瓣更低,主瓣更窄;二是成像方面,点源成像效果更好。 Finally, through the simulation experiment proves that the improved performance of the synthetic aperture system compared to the original ultra synthetic aperture system has greatly improved, mainly displays in: one is antenna array, the array factor of the lower sidelobe, main lobe narrower;Second, the imaging, point source imaging effect is better.
48827 现有的分辨力和调频脉冲串(pulse trains of frequency modulated,PTFM)信号参数间的定量关系是在窄带条件下基于窄带模糊函数给出的。 Existing resolution and frequency modulation pulse sequence (pulse trains of frequency modulated, PTFM) the quantitative relationship between signal parameters is given under the condition of narrow band based on narrow-band fuzzy function.
48828 宽带条件下,应采用宽带模糊函数(wideband ambiguity function,WAF)分析调频脉冲串信号的分辨力,而基于宽带模糊函数的分辨力方程难以直接求解,为此提出一种基于宽带模糊函数的分辨力数值分析方法。 Under the condition of broadband, broadband should be adopted fuzzy function (wideband ambiguity function, the WAF) analysis of frequency modulation pulse sequence signal resolution, and based on the fuzzy function of broadband resolution equation is difficult to solve directly, therefore put forward a resolution in the numerical analysis method based on broadband fuzzy function.
48829 该方法将分辨力表示成各单参数函数的连乘形式,综合运用方程求根和曲线拟合方法,求出单参数函数表达式,进而综合出分辨力的表达式。 This method will represent a resolution LianCheng form of each single parameter function, the integrated use of equation root and curve fitting method, and the single parameter function expression, and comprehensive expression of the resolution.
48830 分析结果表明,该方法可明确给出宽带条件下分辨力和调频脉冲串信号各参数间的定量关系。 Analysis results show that this method can clearly give broadband resolution and frequency modulation pulse sequence signal under the condition of the quantitative relationship between the parameters.
48831 该定量关系可指导调频脉冲串信号参数设计,提出的基于宽带模糊函数的分辨力数值分析方法对于其他形式宽带信号的分辨力分析具有参考价值。 The quantitative relationship is direct frequency modulation pulse sequence signal parameter design, put forward the resolution of numerical analysis method based on broadband fuzzy function for other forms of broadband signal resolution analysis has the reference value.
48832 研究两两方案之间具有严格偏好关系的语言判断矩阵满意一致性判定方法,若不具有一致性给出调整方法。 Research has strict preference relationship between the two schemes of linguistic judgment matrices satisfying consistency judgement method, if not consistent adjustment method is given.
48833 首先,利用语言判断矩阵的0-1型排列偏好关系矩阵是否是上三角矩阵来判定语言判断矩阵是否具有满意一致性; First of all, based on the linguistic judgment matrix type 0 and 1 is arranged on the preference relation matrix is triangular matrix to determine whether the linguistic judgment matrix is satisfied consistency;
48834 接着,给出判断不合逻辑的3个方案比较结果构成循环圈矩阵的定义,在循环圈矩阵的基础上找出构成循环圈的3个方案,根据方案行偏好值的大小对不合逻辑的循环圈进行调整,得出方案的优劣顺序和调整后的语言判断矩阵; Then give judgment illogical three schemes comparison results constitute a cycle matrix is defined, on the basis of the cycle matrix to find a circle three scheme, according to the size of the package line preference values to adjust illogical cycle, the advantages and disadvantages of alternative sequence and adjusted the linguistic judgment matrix;
48835 最后,通过实例验证该方法的合理性和有效性。 Finally, an example to verify the rationality and validity of the method.
