Tuning the Angular Characteristics of Biomimetic Antenna Arrays
IEEE Open Journal of Antennas and Propagation, 2023 The angle estimation capabilities of radar sensors are strictly linked to the antenna spacing between the array elements. A larger array aperture corresponds to a smaller beam width or in terms of the angle estimation a higher phase sensitivity.
