    Abstract :

    RADAR performance is measured by its sensitivity of detecting targets at farther distance and range resolution capability. To improve the detection ability long pulse is needed and to improve range resolution capability short pulse is needed. Thus, there exists trade-off between detection and range resolution. To overcome this problem, pulse compression techniques are employed. Pulse compression can be done either by using frequency modulation or phase modulation to simple pulse. Utilization of frequency modulated pulse compression techniques leads to arousal of high side-lobes at the matched filter output. Presence of high side-lobes leads to target masking in presence of multiple targets. To reduce peak side-lobe levels phase coded pulse compression technique is employed. In this paper, the PSL of various phase coding techniques are compared through simulations in LabVIEW.
