ThreeGorgeIntroduction
- 长江是中国最大河流,干流全长6300公里,流域集水总面积180万平方公里,年平均入海量约9600余亿立方米。从干流长度和入海水量论,长江均居世界第三位。 三峡水利枢纽坝址位于长江干流上游的分界处,坝址控制流域面积100万平方公里,多年平均迳流量4510亿立方米,在世界上已建和在建水利枢纽中,与葛洲坝工程同属坝址年迳流量最大的水利枢纽。 -Yangtze is China's largest river, a total length of 6,300 km of the mai

- 阵元失效会破坏拖曳线列阵的幅相分布,导致阵列的旁瓣级出现明显升高,严重影响了阵列的性能。阵元失效条件下 的波束形成是一个非线性的最小平方的优化问题,对其直接求解非常困难。针对这一情况,提出了一种基于遗传算法的阵元 失效校准方法。算法的基本思想是将失效阵元的权重强制为零,并使得阵列的实际响应与期望响应在主瓣区域相匹配,同时 对阵列响应的旁瓣级作出限制-Failed elements will des仃oy the amplitude and phase distribution and
