摘 要:简洁的二维频谱解析式模型是研究任意构型的机载双基SAR 成像算法的基础。本文提出一种适用于任意构型的机载双基SAR 二维频谱解析表达式,它是通过利用曲线拟合和驻定相位定理得到的。首先,采用泰勒级数定理将机载双基SAR 的斜距史函数等效为双曲线和线性误差补偿函数的复合函数。接下来,利用驻定相位定理得到最终的二维频谱表达式。对于机载双基SAR,上述二维频谱模型是精确且简洁的。最后,通过大量的仿真结果验证了上述二维频谱模型的有效性。

Abstract:A concise two-dimensional frequency spectrum analytic model is the basis of general Airplane-Airplane Bistatic SAR(GAA-BiSAR) imaging algorithm. In this paper,it presents an analytic expression of frequency spectrum for general Airborne-Airborne Bistatic SAR(GAA-BiSAR)derived by utilizing the curve fitting approach and the principle of stationary phase( POSP). Firstly,the overall slant range history of GAA-BiSAR is fitted into a hyperbolic function with linear compensation
function based on the Taylor formula. Then,the POSP is performed to obtain the spectrum expression. The proposed spectrum model is concise and accurate for the GAA-BiSAR. Finally,simulation results with GAA-BiSARdemonstrate the validity of the proposed spectrum model.

摘要:现有供应链资金约束企业融资及运营决策研究,大多忽略对供应链链内盈余资金的运用以及核心企业链内融资协调和控制能力的发挥,制约供应链整体效益提升的研究。本文提出链内信息对称的情景下,由核心企业进行协调,以链内盈余资金作为满足资金约束企业资金需求的首要资金源,并由核心企业向链内资金短缺企业提供信用融资的供应链核心企业主导融资(Financing Led by Core Enterprises)方式。本文分析并对比资金约束零售商在选择无融资服务、向银行直接融资及以FLCE 融资情形下供应链整体的收益,研究发现融资服务能提升供应链整体效益,同时发现大多数情形下资金约束零售商选择FLCE 的供应链整体收益优于直接向银行融资的情形;本文建立FLCE 决融资策模型,通过对模型的分析和求解,得出FLCE 融资利率,零售商最优订货量决策及制造商最优批发价决策。研究结论为决策者提供参考依据。

Abstract:This paper studies the clustering performance of self-organizing feature map,which is known as a topological reserving clustering algorithm in comparing with K-means on a set of artificial data. The conventional clustering method,K-means,is an efficient algorithm in dealing with quantitative data classification,but has been shown a weak and instable convergence to global optimal solution due to different initial settings. The self-organizing map is more robust in achieving the optimal solution due to its unique neighborhood function which has a topology constraint though it can slow down the learning speed. In addition,SOM learning is insensitive to initial values.
