1. First of all, the sidelobe of the array refers to the additional signal generated in the array circuit due to the incomplete charge transfer between photodiodes. The signal appears as stripes or spots on the original image. Observe the images taken by the area camera, especially under the conditions of high contrast and high brightness. The sidelobe of the array will appear around the bright area or at the edge of the bright area.
