In this paper, the authors describe the digitization and front-end digital signal processing scheme for the atmospheric Radar operating at 206.5MHz. The atmospheric Radar operating at this frequency will have the capability to probe upto the lower Stratosphere (20km). In the present paper, the capabilities of digital receiver in performing functions like band-pass sampling at 206.5MHz using 16 bit Analog-to-Digital Converter (ADC) and Field Programmable Gate Array (FPGA) based Digital Down Converter (DDC) are demonstrated through simulation.
