Image compression and storing method of radar video

The invention provides an image compression and storage method for radar videos, wherein, radar trigger signals are led in during processing process of the radar videos and utilized for making the radar videos obtain distance starting points, thereby a plurality of triggered radio videos are made to be aligned on the distance starting points and form an image, and then good image compression effect is obtained by means of an image or video compression algorithm. The radar videos compressed by the method has the advantages of capability of fully utilizing relevancy of the radar videos in the aspect of distance and adjacent triggering, capability of obtaining better compression effect under the condition of the same losses, capability of greatly improving operating time of a radar video recording instrument, and capability of reducing data quantity of the radar videos after data compression.
