Abstract
Doppler Velocity Log (DVL) is one of the important devices which can provide positioning and navigation information for surface or underwater vehicle. The traditional DVL usually uses Janus configuration method to launch four beams along the front, rear, left, and right directions of the vehicle to the seabed, and uses Doppler frequency shift to calculate the speed of the carrier. For traditional phased array DVL, the distance between array elements is usually half of the wavelength, and the angle between two beams in the same direction is 60 degrees. Based on the traditional phased array DVL, an eight-beam phased array DVL was proposed, which forms four beams in two mutually perpendicular directions, so is namely double Janus configuration mode. According to the simulation, it was determined that the distance between the array elements is 0.35 of wavelength, and the angles corresponding to the four beams in the same direction are and respectively. In this way, in two mutually perpendicular directions, the four beams with a smaller angle with the horizontal plane can provide a larger horizontal component, which is more conducive to the calculation of Doppler shift; the four beams with larger angles to the horizontal plane have larger vertical components, so that the received echo signals have larger signal strength, and the advantages of the two types of beams are complementary. At the same time, an eight-beam transducer was made and tested in a pool. The angles of the directional beams are and , which are in good agreement with the simulation results. The corresponding transmitting voltage response is 170.2dB and 170.6dB respectively.
