Milsim-woodsball team radar

Hi all, I'm new here and to arduino, but I'm starting to study this and hope to learn a lot of things. I'm posting here because I hope to try to build in neqr future a team radar, so do you guys think that something like this : http://hackaday.com/tag/zephyreye/. Can be build with arduino? Can someone recommend me what parts or shields should I buy in order to make something similar? My only interest is in tracking me and my team mates, also any advice is welcome

Any help would be very apprecciated.

Thanks in advance
