Adaptive orthogonal projective decomposition in sidelobe suppression

Binary sequences have been successfully employed in spread spectrum communication system (SSCS) and radar detection, and suppression of range sidelobe is a critical technique in SSCS and radar applications. In this paper, orthogonal projective decomposition combined with adaptive technology (AOP) is introduced to sidelobe suppression with its Doppler optimized scheme. Simulation results show that this algorithm achieves better noise rejection ability, higher Doppler tolerance and superior resolution ability with low computational complexity and resource consumption.
