WebElectronically steered array (ESA) radar systems control the direction of transmission or reception using beamforming techniques that change the phase of the elements in an array. Transmitter arrays in ESA radar systems steer radiated energy to improve directivity in azimuth and elevation. WebMar 5, 2024 · My purpose is to rotate the field from the "antenna" reference system (where a phased array lies on the XoY plane) to the "measurement" reference system (where the phased array is rotate and now is "vertical", i.e. on the YoZ plane). So in the first case I expect the main lobe on the z-axis, while in the second along the x-axis.
