Technical Problem
针对此应用需求，现有方法通过对阵列天线各阵元激励的优化合成具有特定形状的宽波束波形，然后再计算器主瓣增益和副瓣电平，因此难以对宽主瓣波束的增益进行控制，从而难以获得给定主瓣增益条件下的最低副瓣特性
Benefits of technology
[0021]本发明的有益效果为：本发明直接以阵列天线的功率增益表达式为约束对象，通过交替迭代方法对阵元激励进行优化，相较于传统的以天线方向图表达式为约束对象的SBPS方法，在获得相同宽主瓣增益的前提下，大大降低了阵列天线的副瓣电平。

Abstract
The application belongs to the technical field of array antennas, and particularly relates to an array antenna wide-beam gain optimization method. The application directly takes the power gain expression of the array antenna as a constraint object, and further reduces the sidelobe level under the condition of the same main lobe gain by optimizing and weighting the array element factor. The application has the beneficial effect that the application directly takes the power gain expression of the array antenna as a constraint object, and optimizes the array element excitation by an alternating iteration method, so that the sidelobe level of the array antenna is greatly reduced under the premise of obtaining the same wide main lobe gain compared with the traditional SBPS method which takes the antenna directional diagram expression as a constraint object.
