The theoretical analysis and experimental research on the port-to-starboard distinguishing technology of the towed line array are given, and two kinds of processing methods for the port-to-port classification of the ternary hydrophone are given. Through the experimental data processing and analysis, the results of theoretical calculations are verified, and the processing algorithm is extended to the broadband situation. The results show that the three-element hydrophone group processing algorithm based on the optimal beamforming theory can distinguish the target left and right navigation, and due to the simple algorithm, it is expected to be practical application.
