分阶段阵列是以模式排列的天线,麦克风或声音传感器的集合。阵列将信号转换为辐射能量以传输到目标。阵列还将传入的能量从源或反射对象转换为信号。阵列的性能在许多方面都超过了单个数组元素的性能。分阶段阵列比单个元素具有三个主要优势:
改进的空间分辨率 - 在定位和成像目标时查看更详细的分辨率。
电子转向 - 使用阵列转向矢量在任何方向上提高检测性能。
干扰抑制 - 采用先进的抑制技术,例如干扰素无效,适应性波束形成和高分辨率方向发现。
You can use the System objects and blocks in this toolbox to construct phased array systems. These objects and blocks include element models, array design models, and radiation and collection models. With these models, you can simulate radar, audio, and sonar systems. While the toolbox emphasizes phased arrays, you can also simulate systems consisting of single antennas, microphones, or transducers. The toolbox also provides models for transmitting and receiving amplifiers.
