RIA: Utilizing Sensor and Wave Properties for Antenna Array Processing

LI为了利用天线阵列获得最佳的估计性能，信号处理算法必须同时考虑传感器和波的特性，并利用这些特性的优势。这项研究的主要目的是：1.利用不同极化敏感阵列的优点；2.发展完全和部分极化波的方向和极化估计技术；3.考虑天线传感器之间的相互耦合效应，进行方向和极化估计，并用天线理论模拟附近的散射体。这些算法正在应用于来自工业和政府来源的模拟和实验数据。正在对这两种类型的数据评估算法的性能。

Li To achieve the best possible estimation performance with an antenna array, signal processing algorithms must consider both sensor and wave properties, and exploit the advantages of these properties. The main objectives of this research are: 1. to exploit the advantages of different polarization sensitive arrays; 2. to develop the direction and polarization estimation techniques for both completely and partially polarized waves; and 3. to take into account the mutual coupling effects between antenna sensors for direction and polarization estimation and for modeling nearby scatters with antenna theory. The algorithms are being applied to both simulated and experimental data from industrial and government sources. The performance of the algorithms are being evaluated for both types of data.
