storing radar video data into a one-dimensional array;
copying data from the one-dimensional array into a radar video data structure;
the radar video data are taken out of the structural body and assigned to a three-dimensional array, wherein the three-dimensional array comprises a distance, an azimuth and an amplitude; the data set required for two-dimensional display includes distance and amplitude;
taking out the data set required by the two-dimensional display from the three-dimensional array and storing the data set into the two-dimensional array;
adding the three-dimensional array data into an array queue for caching;
the graphic display module is used for carrying out two-dimensional graphic display on the radar video according to the two-dimensional data and carrying out three-dimensional graphic display on the radar video according to the three-dimensional data;
when three-dimensional playback is displayed, matching the data set according to the selected distance range, and copying the data in the distance range in all the cache frames in the array queue to the current array;
and when the two-dimensional playback is displayed, copying the data in the selected frame distance range in the array queue to the current array according to the selected distance range.
6. A computer device comprising a processor and a memory, the memory having stored therein a computer program that is loaded and executed by the processor to implement the radar video display method of any one of claims 1 to 4.
7. A computer readable storage medium, characterized in that the storage medium has stored therein a computer program, which is loaded and executed by a processor to implement the radar video display method according to any one of claims 1 to 4.
