This paper proposes a novel detection approach for harmonics in strong additive background noise. Firstly, a wavelet packet transform based filter bank was used to decompose the received noisy signal into several orthogonal sub-band signals. And then, combined with adaptive threshold floating technique, a group of sliding power detectors was applied to detect each given sub-band signals respectively. Simulation results show that the presented method has a good performance in a very low signal-to-noise ratio (SNR) condition.
