A source is encoded into two data streams for transmission to a receiver over two noiseless (or error-corrected) channels.
The far field radiation patterns of open cassegrain antennas have been previously computed by a double integration 1 .
It is well known from our day-to-day experience that distant objects appear to shimmer, especially on still, hot days when relatively large temperature and humidity gradients may exist.
