711雷达没有直观的“分层显示”装置,因此,在取资料过程中,通常的做法是分别拍下不同分贝数的回波照片,必要时才将这些照片排列在一起分析,或者在印放中再加工拼合,这样做不但胶卷相纸用得多,而且麻烦费工。我们现在只在拍片中稍作改革,即可以拍出强回波与0分贝回波合在一起的“分层显示”的照片,使照片的回波形状和结构更加形象直观和准确,
The 711 radar does not have an intuitive “layered display” device. Therefore, it is common practice for the radar to capture echoes of different decibels separately and arrange the pictures together if necessary, In the re-processing of flat, do not only do so much film and paper, but also troublesome work. We are now only a little reform in the film, you can shoot strong echo and 0 dB echo combined with the “layered display” of the photos, the echo shape and structure of the picture more intuitive and accurate image,
