Barker code radar simulation for target range detection using software defined radio

Abstract

This paper present simulation of radar using Barker code signal to provide pulse compression. Barker code is the most well-known phase coding for pulse compression techniques. Pulse compression techniques has been known can provide solution for range resolution and detection range problem. Radar using Barker code simulated using software-defined radio, GNU Radio. Using GNU Radio give flexibility in operation, lower costs, faster in the realization of the design and easier to use. Radar signal processing for received signal performed on MATLAB. Radar used to detect range of the target which simulated by delaying the signal. This radar using Barker code length of 13. PRI 1.3×10-2 using for this radar, which give maximum unambiguous range 1950 km. Barker code signal of transmitter delayed 3000, 5000 and 10000 samples for simulation of target. Radar can detect the target as seen from the results of the signal processing done on matlab.
