- 由于圆形阵列所具有的特性，使其正得到日益广泛的应用，但是圆阵方向图却具有 相对主瓣较高的旁瓣电平。为此，本文针对均匀圆形阵列的天线单元，应用遗传算法,分别 进行唯相位、唯幅度、相位-幅度的方向图综合方法，进行旁瓣电平的优化。仿真结果表明： 这些方法可有效地降低圆阵的旁瓣电平，为解决此类问题提供了有益的参考。 -Circular array of features, are being increasingly widely used, but the circular arra

Array-beamforming-optimization
- 本文给出了一种利用幅相加权对阵列天线进行全局优化的方法。为了使天线的辐射波束形成给定的 方向图，采用联合应用DFP和BFGS公式的变度量算法对阵列天线各单元的馈电幅度和相位分布进行优化， 通过C++语言编程计算实现，从而使得优化后的阵列天线主波束形状能够与预给波束形状相吻合，达到设计 要求。全局优化是本文的特色，它弥补了局部优化结果的精确度依赖于初始值的缺点，因而得以保证通过优 化得到的天线主波束与给定波束的主瓣相吻合，副瓣也得到有效控制。该方法具有快速收敛，计算量小等优 点

- 雷达技术是在1987年前后开始应用于储油罐液位测量的。在此之前,它主要用于航海远洋油轮的液位测量,而与用于油罐的测量则有一定差别。从那时起,雷达测量仪器被广泛应用,从测量简单、清洁的产品到粘性产品和污染性产品,如沥青、焦油和未经加工的蜡等。其测量过程是,先建立一个稳固的测量参考点,然后测量雷达波从天线到液面的往返传播时间,从而确定它们之间的确切距离,再根据测量参考点的位置,就能推算出精确的液面位置。 更多还原 -Radar technology in 1987, used in oil ta
