the lowest region of the ionosphere (35 to 50 miles up) that reflects low-frequency radio waves
d-layer Sentence Examples
- The d-layer of the ionosphere reflects radio waves in the frequency range of 5-10 MHz.
- The height of the d-layer varies with altitude, time of day, and atmospheric conditions.
- The d-layer is heavily influenced by solar radiation, with ionization levels increasing during the day and decreasing at night.
- The d-layer is responsible for the phenomenon of near-vertical incidence skywave propagation (NVIS).
- Radio waves reflected by the d-layer can be used for short-distance communication, especially at low frequencies.
- The d-layer plays a crucial role in long-distance radio navigation systems, such as LORAN and VOR.
- The d-layer's strength and characteristics affect the range and quality of over-the-horizon radar systems.
- Sporadic ionization in the d-layer can sometimes result in signal fading and interference in radio communications.
- The ionosphere's d-layer is constantly being studied and monitored, as it has a significant impact on radio propagation.
