1 IntroductionSonar can accurately detect fixed targets and determine target distance, it has poor concealment and limited range and is susceptible to reverberation interference. The detection signal emitted by active sonar encounters obstacles or targets in the propagation path of water, and is then affected by reflection, refraction, and scattering, resulting in signal delay and overlap.

Abstract:The performance of the underwater acoustic (UWA) orthogonal frequency division multiplexing (OFDM) system is often restrained by time-varying channels with large delays. The existing frequency domain equalizers do not work well because of the high complexity and difficulty of finding the real-time signal-to-noise ratio. To solve these problems, we propose a low-complexity neural network (NN)-based scheme for joint equalization and detection.
