摘要：In Pulse radar receiver system Digital down converter is an important part. Digital down converter(DDC) demodulates the base band signal from the transmitted signal and also reduces the sampling rate of the signal.The most important part of DDC is filter structure, it uses large resources which increases the cost of the system. Toovercome this problem we propose the new filter structure containing the low pass FIR Half-band filter. The proposedfilter structure of DDC reduces the complexity and cost of implementation. The simulation results shows that theproposed filter structure of DDC achieves expected specification in application of pulsed radar receiver.
