Wind profiler radar is also a pulsed Doppler radar which also analyses the reflected electromagnetic signal to determine the wind velocity. Wind profiler system follows Bragg’s principle according to which, an electromagnetic wave can be scattered by the particles having size half the wavelength of an incident electromagnetic wave. Irregularities exist in a size range of a few centimeters to many meters. Hence the frequency of the wind profiler is kept in the range of 30MHz -3000 MHz. Here the proposed system works at the frequency of 50 MHz. As the basic structure and signal processing of the both Ionosonde and Wind profiler is same, we can utilize the hardware of the Ionosonde to construct Wind profiler radar with few modifications. The paper discusses the signal processing done in the Ionosonde and the modification need to be done in the embedded hardware to utilize it as Wind profiler radar.
