lóbulo lateral
1. In antenna or signal processing, a secondary lobe of radiation or response pattern that appears adjacent to the main lobe, typically with lower intensity
The antenna design minimizes side lobes to reduce interference with nearby frequencies.
O design da antena minimiza os lóbulos laterais para reduzir interferência com frequências próximas.
2. In audio engineering and acoustics, unwanted secondary peaks in a frequency response or directional pattern
Engineers must control side lobes in microphone arrays to improve signal clarity.
Os engenheiros devem controlar os lóbulos laterais em arranjos de microfones para melhorar a clareza do sinal.
3. In radar systems, spurious signals or echoes that appear away from the main beam direction
Radar systems suppress side lobes to avoid false target detections.
Os sistemas de radar suprimem os lóbulos laterais para evitar detecções falsas de alvo.
This is a highly specialized technical term used primarily in engineering, telecommunications, radar, and signal processing fields. It is universally understood in the same way across English-speaking countries and Brazil, with no regional variations in meaning. The term is predominantly used in academic and professional contexts rather than in everyday communication.
