Abstract :
In this work a customized digital hardware function unit is developed for saturation correction in weather radars. This unit acts to assure wide dynamic range of the radar receiver as AGC unit does in analog circuitry. To meet the requirement for real time processing, FPGA device is employed with VHDL design. Several experiments were conducted and the results show that receiver´s dynamic range increment is more than 6 dB
