Macgregor S. Reid

Low-Noise Systems in the Deep Space Network

€ 248.95

This book explores the low noise microwave systems that form the front end of all DSN ground receiving stations. It explains why the front end of each antenna is key to establishing the sensitivity, polarization, frequency diversity, and capabilities of the receiving chain and, therefore, the entire ground station.
