Atmospheric Effects on Signals
2017The atmosphere causes several serious negative effects upon radio signals, and these effects are very dependent on three things. The first factor is the frequency in use: some frequencies - the lower ones - are hardly affected; higher frequencies are greatly affected.

Ultrasonic proximity sensors are a good compromise in terms of cost, energy efficiency, and accuracy for low distance obstacle detection. Various fields of interest could find this book interesting, for example, structural damage inspections in critical areas (e.g., L’Aquila earthquake, Italy, or hurricane Ike in Galveston, Texas, US).
