Abstract
Pulse compression is used to achieve large radiated energy but simultaneously a short pulse for range resolution. Range resolution is an ability of the receiver to detect nearby targets. Pulse compression can also detect small target signals out of clutter. The matched filter output consists of unwanted but unavoidable side lobes however the reduction of this side lobe strength is the active research topic in radar signal processing. In this paper a new technique is proposed to suppress the side lobes of radar signals that result from standard matched filtering. In this technique, it produces better peak side lobe ratio than all other conventional side lobe reduction techniques. In simulation results, the performance of this filter technique for Barker codes is compared with the amplitude shift code side lobe reduction technique.
