This article deals with a design and analysis of an 8‐element dipole array for passive coherent location (PCL) systems. The array is composed of eight identical dipole elements that are arranged at a radius of 0.5λ₀ from the center to the elements. To verify the performance for the PCL system, the array is fabricated and measured in an outdoor test site. Array performances such as the antenna gain, peak to side lobe ratio (PSLR), half‐power beam width (HPBW), null width, and null depth are then analyzed. The results demonstrate that the proposed array has beam pattern characteristics suitable for PCL systems.

无源相干定位系统的8元偶极子阵列的设计与分析

本文讨论了用于无源相干定位（PCL）系统的8元素偶极子阵列的设计和分析。所述阵列由被布置在0.5λ的半径八个相同的偶极子元件的₀从中心到的元素。为了验证PCL系统的性能，在室外测试现场制作并测量了阵列。然后分析阵列性能，例如天线增益，峰旁瓣比（PSLR），半功率波束宽度（HPBW），零宽度和零深度。结果表明，提出的阵列具有适用于PCL系统的波束方向图特性。
