underwater common wideband sound source 6-element circular array received dataset

The dataset consists of experimental data collected in an anechoic tank, with a specific setup involving single-source transmission and reception by a 6-element circular array with a radius of 0.046 meters. The transmitted signals include common wideband signals used in underwater positioning and communication, such as chirps, single-carrier QPSK, multi-tone signals, and OFDM signals. The transmitter and receiver are located at the same depth, and the receiving array rotates 360 degrees with 30-degree intervals. Two sets of scenarios are defined with transmission distances of 4 meters and 19 meters, as detailed in the dataset's documentation. This dataset can be utilized for the design and optimization of wideband sound source Direction of Arrival (DOA) estimation algorithms.
