Research into the Errors of Distance Determination under Water with the Phase Radioengineering System with Regard to the Depth of Immersion

The operation of the phase radioengineering system of the distance determination under water is considered in the paper. The system is built with the use of reference electromagnetic and information hydro acoustic underwater channels. The propagation of acoustic waves under water is а complex process. There are several acoustic waves at the receiving point due to multiple reflections. Reflection from the sea surface affects acoustic waves. The measure of inaccuracy of distance determination in information acoustic channel is calculated with regard to the depth of acoustic transducers immersion. The main limitations in the range determination process are established and ways to eliminate errors are indicated.
