| 摘 要： | 为解决传统天线展宽方法在相控阵雷达应用中的不足，文章提出一种通过减少阵元数的方法展宽天线波束宽度。通过理论分析该方法的可行性，在此基础上分析了由于天线展宽带来的主副瓣比下降和雷达威力下降的问题，并提出改进的办法。

| Abstract: | This article has presented a method, which based on reduce the number of array elements, to solve the shortage of the application of conventional methods of Beam Broadening on Phased-Array antenna. It was proved this method was available. Then made a emphatically analyze on the problem of decline of the Main-Sidelobe ratio and the radar true range, a method has presented to improvement it. |
