Improving the G/Ts of radio telescopes and radiometers and their associated receive subsystems translates into increasing the ground received signal-to-noise ratios. Therefore, low noise amplification with cooling operation is required. However, the system designer must select an appropriate feedhorn antenna with low sidelobes and an adapted illumination at the edge of the reflector since the noise originated from the surroundings will be collected by the horn and added directly to the overall… CONTINUE READING
