Abstract
A computer based drift radar system has been designed for real time ionspheric irregularities measurements where closely spaced receiver technique has been utilized. A computerized interface with the system a long with real time software has been developed to keep tracking of the measured data for further analysis. The system has been implemented at locations and produced a reliable analysis.
Highlights
Radio communication especially at low frequency and high frequency ranges depends intimately on the characteristics of the ionosphere
One of the most widely employed methods to measure the drift of the ionspheric irregularities, is the closely spaced receiver technique (D1).this technique records the amplitude of the reflected signal simultaneously at three closely spaced points on the ground .The radio waves are transmitted vertically upwards from a pulse transmitter
Comparison of the closely spaced receiver technique (D1) with rocket techniques, meteor radar technique, back scatter radar and incoherent radar techniques has indicated that this technique gives a reliable estimate of average wind velocity in ionspheric D,E and F regions[2,3]
Summary
Radio communication especially at low frequency and high frequency ranges depends intimately on the characteristics of the ionosphere. One of the most widely employed methods to measure the drift of the ionspheric irregularities, is the closely spaced receiver technique (D1).this technique records the amplitude of the reflected signal simultaneously at three closely spaced points on the ground .The radio waves are transmitted vertically upwards from a pulse transmitter. When these waves travel through these irregularities, phase modulation takes place and the returned waves form a diffraction pattern too.
