In antenna engineering, sidelobes are the lobes (local maxima) of the far field radiation pattern of an antenna or other radiation source, that are not the main lobe.. The radiation pattern of most antennas shows a pattern of "lobes" at various angles, directions where the radiated signal strength reaches a maximum, separated by "nulls", angles at which the radiated signal strength falls to zero.
2.6 Decoding Performance. c. Side-lobe Suppression. The transponder must be suppressed for a period of 35 ±10 microseconds following receipt of a pulse pair of proper spacing and suppression action must be capable of being reinitiated for the full duration within 2 microseconds after the end of any suppression period.
When jamming is strong enough, the radar receiver can detect it from a relatively low gain sidelobe. The radar, however, will process signals as if they were received in the main lobe. Therefore, jamming can be seen in directions other than where the jammer is located. To combat this, an omnidirectional antenna is used for a comparison signal ...
Side-lobes are produced during signal processing and a side-lobe suppression strategy, such as Dolph–Chebyshev window function, is required to reduce false alarms . [1] All of the samples taken from the Sample 1 sample period form the input to the first set of filters. This is the first ambiguous range interval.
Going for the 3-peat. The Chiefs are certainly aware of what's in front of them Sunday.But the players said they've been able to keep the focus on the challenge in front of them every week.
A federal appeals court ruled that the Justice Department can release a report on Donald Trump’s efforts to overturn his 2020 election loss, but kept in place a judge's order requiring a three ...
SSR antenna of Deutsche Flugsicherung at Neubrandenburg, in Mecklenburg/Western Pomerania Transponder in a private aircraft squawking 2000. Secondary surveillance radar (SSR) [1] is a radar system used in air traffic control (ATC), that unlike primary radar systems that measure the bearing and distance of targets using the detected reflections of radio signals, relies on targets equipped with ...
