Underwater Small Target Detection Method Based on the Short-Time Fourier Transform and the Improved Permutation Entropy
In the realm of underwater active target detection, the presence of reverberation is an important factor that significantly impacts the efficacy of detection. This article introduces the improved permutation entropy algorithm into the analysis of active underwater acoustic signals. Based on the sign...
