相信大家已经注意到了,伴随着微观金融理论的发展,以随机分析为核心的数学理论
也在同步发展,并不断为金融学家们所吸收和运用,它们交织在一起,密不可分又相映生
辉②。它们相映生辉倒不要紧,但就给研究者带来了很多困难:由于微观金融学研究重点的
特殊性和复杂性(不确定性和动态性),注定以随机分析作为其主要数学工具,这无形中提
高了这一学科的门槛③。

MIMO雷达波束图与波形的关系
仿真研究了MIMO雷达发射波束图和波形相关程度的关系。波形相关程度越高发射波束图越窄,发射能量越集中;波形相关程度越小,发射波束图越平坦,发射能量在空域分布越均匀。(Relation between Degree of correlation of waveform and transmitting beampattern. Hign correlation of waveforms corresponding to concentrated transmitting energy; Low correlation of waveforms corresponding to concentrated evenly distributed transmitting energy.)
