Trying to overlay a radar image(radar projection) on a mercator projected map, but have no idea about what a radar projection is.

So here are my quesions:

What is a radar projection?

What's its forward/backward formula?

Does proj4 or gdal/ogr support this projection?

There are multiple radar presentation formats (from the A-scope up to more "understandable" formats). It might help if you can edit your question (using the edit link above) to tell us more about your data. For example, where did you get the data? Can you make a sample public? –  BradHards Feb 20 '13 at 1:56
    
@BradHards , the radar image is a PPI display and already scan converted. I've been only told it's a "standard radar projection". So I think its just some normal raster under some projection. –  feverzsj Feb 20 '13 at 2:07
    
Perhaps, but I'm not convinced that there is any such thing as a standard for radar projections, so you'll need to go back to the source, or perhaps consider posting a sample that someone may recognise. –  BradHards Feb 20 '13 at 9:47
    
It is striking that Google cannot find any instance, anywhere, of the phrase "standard radar projection"! –  whuber Feb 20 '13 at 17:37
