Abstract

Pulse compression technique is usually used in RADAR system in order to raise the signal to noise ratio (SNR) improving the target detection and range resolution Because of masking of small targets by the side lobes of large nearby targets, a problem may arise in pulse compression technique. This paper has proposed a technique to suppress the side lobes by using a transversal filter in digital pulse compression and compared the result of analog and digital pulse compression technique. It is revealed that the digital pulse compression with transversal filter is better for reduction of side lobes of nearby targets.
