Introduces the basic concept of polarization. It shows how to analyze the polarized field and model the signal transmission between polarized antennas and targets using Phased Array System Toolbox™.

模式乘法原理指出，数组的辐射模式可以视为元素模式和数组因子的乘法。但是，当天线被部署到阵列中时，其辐射模式会被其相邻元素修改。这种效果通常称为相互耦合。因此，为了提高分析的保真度，应该在模式乘法中使用具有相互耦合效果的元素模式，而不是隔离元素（本身位于空间中的元素）模式。

使用无限阵列分析对大有限阵列进行建模。对晶胞的无限阵列分析揭示了特定频率的扫描阻抗行为。该信息用于了解隔离元件模式和阻抗以计算扫描元件模式。然后，使用以下假设对大的有限阵列进行建模：阵列中的每个元素都具有相同的扫描元件模式。

Model a 77 GHz antenna array for frequency-modulated continuous-wave (FMCW) radar applications. The presence of antennas and antenna arrays in and around vehicles has become commonplace with the introduction of wireless collision detection, collision avoidance, and lane departure warning systems. The two frequency bands considered for such systems are centered around 24 GHz and 77 GHz, respectively. In this example, we will investigate the microstrip patch antenna as a phased array radiator. The dielectric substrate is air.

Model and visualize a variety of antenna array geometries with Phased Array System Toolbox™. These geometries can also be used to model other kinds of arrays, such hydrophone arrays and microphone arrays. You can view code for each plot, and use it in your own project.

The Sensor Array Analyzer app lets you examine important properties of a phased array such as response and geometry.
