Abstract

In this paper, exploitation of parallel MATCHED FILTERs bank based on binary phase code is proposed, to overcome shift Doppler in ground based radars which use pulse compression technique. The mismatch loss due to target Doppler shift in radar receiver reduced by odd or even number of these parallel filters. By increasing the number of filters over target velocity axis the central Doppler frequencies of the neighbor filters approach together and consequently the overlap increases and results in the straddling loss decrease in output. Using MATLAB software, the attenuation in the output of the receiver MATCHED FILTER due to airborne target velocity was analyzed and a solution to calculate minimum number of filters is proposed for minimum loss of SNR. Finally, two methods for implementation of parallel MATCHED FILTERs on FPGA in the airborne targets radar receiver are presented and compared.
