How to display the overlapping parts of radar images?

The radar map needs to be superimposed and displayed based on openlayers.

The overlay of the radar mosaic on OpenLayers shows that the radar mosaic was released by the Meteorological Exploration Center of China Meteorological Bureau in the system of weather radar mosaic v3.0, and a transparent PNG picture was taken at each observation time.

For static image loading, OpenLayers provides the support of ol.source.ImageStatic. You can refer to the official demoImageReprojection and demonstrate the concrete realization of image superposition and projection adjustment.
