One radar that has gained popularity due to its ability to scan a large field of view is the phased array radar (PAR). [One] traditional PAR [is] known as a passive electronically scanned array (PESA). In the PESA, a single transmitter generates a high-powered signal that is transmitted through individual antenna elements. Each transmit element has an associated computer-controlled phase shifter ... that creates a directional beam by adding a phase shift to the signal from each element. The narrow beam is sequentially steered through the field of view by changing the phase at each element. 4, record 1, English, - passive%20electronically%20scanned%20array
