Usage of the Gstreamer framework for generation, analysis, processing and visualization of sonar signals

In this paper, the usage of the GStreamer framework in applications of classical digital signal processing is discussed. Especially, its adaptation for the sonar technique is presented. Signal generation, analysis, processing, and visualization are implemented as GStreamer plugins. The new plugins and the structure of data transmitted through a GStreamer pipeline are briefly discussed. The introduced plugins are published as free software under the GROJ project.
