Question

A pulse of given frequency transmitted upwards is received back after a peroid of 5msec. Find the height of reflecting layer.​

Answer 1

Explanation:

General

The temporal and spatial variation in ionospheric structures have often frustrated the efforts of communications and radar system operators who base their frequency management decisions on monthly mean predictions of radio propagation in the high frequency (short-wave) band. The University of Massachusetts Lowell’s Center for Atmospheric Research (UMLCAR) has produced a low power miniature version of its DigisondeTM sounders, the DigisondeTM Portable Sounder (DPS), capable of making measurements of the overhead ionosphere and providing real-time on-site processing and analysis to characterize radio signal propagation to support communications or surveillance operations.
