Amplitude Shifting for Sidelobes Cancellation Pulse Compression

Pulse compression has been used to improve radar resolution. Many techniques are involved in pulse compression and they fall under frequency modulation and phase modulation. All of the techniques that have been implemented so far suffer from the sidelobe phenomena including Barker code, which uses a phase modulation technique. Mismatch filter is used to minimize sidelobes. Using mismatch filter increases hardware complexity, area, cost and power consumption and also degrades the performance. Not only that, sidelobe reduction takes place at the expense of signal to noise ratio loss. Amplitude shifting technique is proposed to cancel the sidelobes of Barker code completely without any loss in signal to noise ratio and with much less hardware complexity, area and cost. Elimination of mismatch filter reduces the power consumption and improves the performance
