Gap free CONUS surveillance using dense networks of short range radars

Dense networks of short-range radars having the potential for improved surveillance of weather and airborne targets are described. Such networks overcome the earth-curvature blockage suffered by long-range radars. This enables surveillance from the region beneath the radar coverage of today's national radar infrastructure, up through the tops of storms and flight levels. Such networks have the potential to supplement - or replace - the long range radar networks in use today.
