Side echoes[ :] Squeezing a... multi-directional radio wave into a directional radar wave is never fully achieved. Not all of the radar wave can be focused by the radar aerial into the main lobe. Some escapes into what are known as side lobes. Side echoes are caused by reflections from the side lobes of the radar beam. They are likely to appear when a target is a good radar reflector and in range of the weaker side lobes. 2, record 1, English, - side%2Dlobe%20echo

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 2, English, - passive%20electronically%20scanned%20array
