Abstract

Determining the third dimension of the underwater targets, by the sonar system, can play an important role in three dimensional imaging and target recognition. In this paper, by applying the Inverse Synthetic Aperture Sonar and using the seabed virtual source and a second sensor, the third dimension of the targets is obtained. For obtaining the third dimension, we use the distance between the scatterer and its two main corresponding artifacts in the two dimensional image. In the case of having two sonar systems, with both the transmitting and receiving roles, the third dimension resolution is increased obviously, compared to the monostatic case explained in our previous paper. In addition, because of having these two sensors, more target scatterers will be in the view of sensors. By using the information obtained in this way, it is possible to achieve more accuracy in calculating the third dimension and create a three-dimensional image of the target. Because of the importance of the underwater monitoring, using the proposed scenario, we can use this system for more accurate identification of the targets to counter the threats and for the defence applications.
