一种基于四相编码和优化阵列的MIMO STAP实现方法

多输入多输出（MIMO）雷达多信号间正交性和天线阵列结构影响空时自适应处理(STAP)性能。为了提高多信号间正交性,提出了基于遗传算法优化提高四相编码的自相关峰值并降低互相关峰值方法,保证了多发射信号间良好正交性,基本抑制了盲速影响。针对天线阵列稀疏导致盲速、阵元密布导致天线孔径过小的问题,基于最大连续孔径思想,提出了一种优化阵列结构,在不显著增加天线阵列长度和阵元数目条件下,与四相编码信号结合,实现了动目标检测。仿真实验证明,基于四相编码正交信号和收发阵列设计,MIMO STAP可实现良好动目标检测性能。     

Capital Inflows,Exchange Rate Flexibility and Credit Booms

Historically, capital flow bonanzas have often fueled sharp credit expansions in advanced and emerging market economies alike. Focusing primarily on emerging markets, this paper analyzes the impact of exchange rate flexibility on credit markets during periods of large capital inflows. It is shown that bank credit is larger and its composition tilts to foreign currency in economies with less flexible exchange rate regimes, and that these results are not explained entirely by the fact that the latter attract more capital inflows than economies with more flexible regimes. The findings thus suggest countries with less flexible exchange rate regimes may stand to benefit the most from regulatory policies that reduce banks' incentives to tap external markets and to lend/borrow in foreign currency; these policies include marginal reserve requirements on foreign lending, currency‐dependent liquidity requirements and higher capital requirement and/or dynamic provisioning on foreign exchange loans.     

浅议绿色高端农业市场的出现和发展

随着市场经济的发展,市场细分不仅存在于商业运营中,传统的农业也逐步从低端向差异化发展,特别是近期绿色高端农业市场的出现及对生产和消费产生的影响趋势愈加明显,而这一市场的出现将对农业种植(养殖)、中间商和消费者带来新的观念冲击,并呈现出勃勃生机.     

论信息处理在个人发展中的作用

当今社会可谓是一个信息社会,信息爆炸以及信息污染这两种现象就是对这一时代的有力诠释。生活在信息环绕之中的个体,如何处理信息,对于自身发展具有重要的影响作用。本文就信息处理的重要性、信息处理的差异性以及如何有效地进行信息处理以推动个人发展三个方面进行了简要论述。     

Global Warming and German Agriculture Impact Estimations Using a Restricted Profit Function

This study uses the concept of shadow prices formeasuring the impacts of climate change. By estimatinga restricted profit function rather than a cost or aproduction function the explanatory power of the modelis increased because of an endogenous outputstructure. Using low aggregated panel data on WesternGerman farmers, the results imply that the agricultural production process is significantly influenced by climate conditions. Simulation results using a 2 ×CO₂ climate scenario show positive impactsfor all regions in Germany. Interestingly, the spatialdistribution of the gains is indicating no advantagefor those regions, which currently suffer frominsufficient temperature. Finally, the importance ofan endogenous output structure is confirmed by thefinding that the desired product mix will drasticallychange.     

基于传统文化的企业创新文化——以海尔创新文化为例

一、基于传统文化的企业创新文化创新成为大多数公司渴望拥有的特征。但是要创新,了解创新的过程是至关重要的。早期对创新过程的研究强调了研发对产生创意的必要性。(Griliches(1998),Mansfield(1984),Rosenberg(1972))。公司的研发支出与创新之间存在一定的关系,然而这种关系     

区域主导与非主导产业协同竞争演化均衡分析

主导产业是区域经济发展的核心，它是区域经济发展的决定性力量。主导产业的发展与更换过程，是区域经济系统内各个产业之间协同竞争作用的结果。因此分析区域主导产业与非主导产业的协同竞争行为所遵循的规律对区域经济发展而言具有重要的理论与现实意义。基于区域产业间协同竞争行为与生物种群之间协同竞争行为机理的相似性，本文运用演化博弈论建立演化博弈模型，对区域主导与非主导产业的演化机制进行分析。     

科技创新“浪潮”之魂

领跑中国PC 1982年，“浪潮”对中国、国际两个市场进行了深刻分析和论证，敏锐洞察到“信息时代”的来临和其中蕴藏的巨大发展机遇。于是果断做出“涉足信息产业，开发和生产微型计算机，抢先在中国占领一席之地”的战略决策。当时，“浪潮人”毅然将上面拨的10万元指定做收录机研发的“救命钱”全数“悄悄”投入微型计算机的研发，从而揭开了“浪潮”以技术创新走向辉煌的序幕。
