The new acoustic sensor represents a major advancement in underwater detection capability. By harnessing the enhanced properties of third-generation single crystal materials, the hydrophone delivers 9 dB greater sensitivity compared with conventional ceramic PZT hydrophones. This improved performance enables longer detection ranges and clearer signal processing, particularly in complex and noisy undersea environments. Designed for next-generation naval sensing systems and advanced ocean monitoring applications, the technology supports improved situational awareness and more precise acoustic detection for submarines and underwater platforms.…
