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 results show that the smart antenna can efficiently strengthen useful signal, decrease interference and form the optimum directivity diagram.

Two coherent signals with different primary phases radiated by two orthogonal in-space linear polarization antenna elements form an elliptical polarization wave.
