A deep dive into what Phased Array technology is, and what it can deliver.

Teledyne RD Instruments 2D Phased Array technology has pushed back the practical, mechanical limits for transducer size and frequency at both ends of the size continuum. This expands the scope of ADCP and DVL performance and widens the range of configurations while still making four different measurements simultaneously-- two from an acoustic pulse profiling the water column (velocity profile, echo intensity profile), and two from a bottom-tracking (BT) pulse (velocity over bottom, altitude above bottom). In this session, Teledyne consider measurement capabilities using Teledyne RDIís 2-d Phased Array technology.

✓ For ADCPs, Phased Array technology permits longer range profiling (800-1000 m) at lower frequencies (38, 45 kHz). This enables measuring deep-water currents that can reveal previously unseen patterns of deep circulation.

✓ For DVLs, Phased Array technology permits increased performance in smaller configurations.
