Beamwidth is a measure of the width of the radiation pattern of an antenna. For SAR [Synthetic Aperture Radar] applications, both the vertical beamwidth, affecting the width of the illuminated swath, and the horizontal or azimuth pattern, which determines, indirectly, the azimuth resolution, are frequently used. Beamwidth may be measured in the one-way or two-way form and in either voltage or power. 6, record 4, English, - beamwidth

Deux systèmes caractérisent les radars latéraux. Le radar à ouverture réelle, et le radar à antenne synthétique. Les facteurs intrinsèques au système radar qui influencent le potentiel de celui-ci sont entre autres : les longueurs d'onde utilisées par le capteur actif, la polarisation de ces ondes, l'angle de visée, l'angle d'incidence, et la résolution.
