Design and Fabrication of a Compact Solid State HF Receiver for Doppler Studies

Abstract

A phase coherent receiver for recording the phase path variations of the reflections from discrete region of ionosphere is described. The design considerations, actual design, fabrication and testing are presented. Some typical data obtained with the receiver is also presented.

Indexing terms:

• Ionosphere
• Doppler
• Radar
• Phase path
• Vertical plasma velocity
• Drift velocity
