Welcome to WaGRL

Washera Geospace and Radar Science Laboratory (WaGRL), which was established in 2007, is a research laboratory and a training center at Bahir Dar University, Bahir Dar, Ethiopia.                      

Radar Systems

Radar fundamentals, radar cross section, radar detection, radar waveform analysis, pulse compression, radar wave propagation, clutter, radar antennas, target tracking.

Review of probability theory, filtering, Bayesian estimation techniques, the Kalman filter, non-linear filters, modified gain techniques, Wiener filters, adaptive methods. 

space physics

This course fouces on recent theories in space physics. The topics include, the Sun, interplanetary space, magnetosphere, electrodynamics of the low-, mid-, and high-latitude ionospheres, equatorial and auroral electrojet currents and plasma instabilities, equatorial spread F, plasma instabilities, waves and instabilities at mid-latitudes, ionospheric scintillation, high-latitude plasma convection, magnetosphere ionosphere coupling.

Computational Physics

Brief overview on computer and its role in Physics teaching and research, MATLAB Usage and computational errors, System of Linear Equations, Interpolation and Curve Fitting, Non-linear Equations, Numerical Differentiation and Integration, Numerical solutions of Ordinary Differential equations and Partial differential equations, Stochastic methods, special functions and quadrature.

GNSS receiver

The receiver is installed in collaboration with Gemany Aerospace center (DLR). It is a high rate sampling GNSS reciever and gives the scintillation index (S4) and total electron content (TEC) data.

Riometer

Riometer measures the amount of electromagnetic wave ionospheric absorption in the atmosphere. Installed in October 2014 in collaboartion with Sodankyla Geophysical observatory in Finland.

Weather station

This weather station is used to observe the humidity and the temperature at the location of the infrared sensor.
