Abstract
Techniques are disclosed for systems and methods to provide dynamic threshold sonar systems for mobile structures. A dynamic threshold sonar system may include sonar equipment configured to capturing sonar data by receiving and converting acoustic returns into arrays of time differentiated sonar data samples, and a processor communicatively coupled to the sonar receiver. The processor may be configured to receive the sonar data samples and determine noise characteristics of the sonar data. The processor may determine a threshold for surface detection based on the noise characteristics and detect a surface, and determine a distance to the surface, based on a comparison of the sonar data to the threshold that has been determined based on the same sonar data.
