Direction of Arrival Estimation Using Two Hydrophones: Frequency Diversity Technique for Passive Sonar

The traditional passive azimuth estimation algorithm using two hydrophones, such as cross-correlation time-delay estimation and cross-spectral phase estimation, requires a high signal-to-noise ratio (SNR) to ensure the clarity of the estimated target trajectory. This paper proposes an algorithm to a...
