Minimum-noise maximum-gain telescopes and relaxation method for shaped asymmetric surfaces

For future low-noise receivers, future radio telescopes must avoid the pickup of ground radiation, and for obtaining the maximum gain with a given diameter, they should be shaped two-mirror systems. A configuration with a double asymmetry is suggested, which would improve the signal-to-noise ratio b...
