摘要
针对干扰方向在某个角度区域内不能精确估计的工程实际问题,可应用宽凹陷波束赋形技术提高信噪比。根据共形球面天线阵列的阵元位置分布,提出了一种适用的宽凹陷波束赋形和凹陷宽度计算机测量技术。建立了该优化问题的适应度函数模型并应用遗传算法优化设计了赋形波束,仿真结果论证了遗传算法进行波束赋形和测量的有效性和稳健性,并拟订了波束凹陷宽度的计算机测量系统。
Abstract： Under some circumstances the value of the parameter is not very accurate, widening the interference null technology can help to improve the SNR of the received signal. According the positions of antenna element on spherical arrays, an applicative beam forming and measurement technology to resolve the problem of the conformal arrays is provided in this paper.- The fitness function of the Genetic algo- rithm is founded and the optimization technical has been applied for Beam groove design. At last computer measurement system solutions have been put forward to measure the beam groove width value.
