3.2.2. AOA Measurement

The AOA is calculated by the positional relationship between the sensor and the target position. The difference in the AOAs of the sensor array is calculated by combining the measurements of the two sensors:

$$\delta\_{q} = \left| \arctan\left(\frac{y\_{i} - y\_{q,1}}{x\_{i} - x\_{q,1}}\right) - \arctan\left(\frac{y\_{i} - y\_{q,2}}{x\_{i} - x\_{q,2}}\right) \right|. \tag{21}$$
