While most conventional airborne radars rely on some form of mechanically scanned antenna to transmit and receive signals, active electronically scanned array (AESA) sensors employ a fixed aperture.
The beam scan with variable linear polarization directions of antenna arrays using MM/C transmit-receive (T/R) modules is explored.
