Summary

Description
Français : Image radar montrant de forts retours venant de collines par temps clair. Les échos centraux très forts (rouge) sont compris dans des arcs de cercle plus ou moins long de réflectivités plus faibles (vert) qui sont dues aux lobes secondaires du faisceau radar.
English: Radar echos, in this case from a series of small hills in the Montreal region called "Monteregiennes". The central stronger part of the returns are from the main lobe but the decreasing intensity in arc on each side are from secondary lobes which are mistakenly placed at the position where the main lobe is when those returns come back to the radar.
