Abstract: Aiming at the features of wind profiler radar for UHF frequency,an efficient and high performance digital receiver based on orthogonal sampling is designed.Through theoretical analysis of orthogonal sampling receiver,quadrature sampling theory,IQ separation operation,half-band filter,etc are introduced in this paper.Finally,simulation results show that digital receiver using orthognal sampling technique is feasible and efficent.
