PRODUCTS

Extreme Sonar periodically releases new products for the sonar market. Current products include a Directional Ultra-Wideband Blade Sensor and a 200-Watt Wideband Power Amplifier / Ultrasonic Pulser with FHSS Waveform Generator.

Extreme Sonar Directional Ultra-Wideband Blade Sensor

​

  • Hydrophones: Seven (7) in hexagonal array

  • Hydrophone Spacing: 1.5" center to center

  • Spacial Coverage: Up to 80 degrees off boresight

  • Usable Frequency Band: 100Hz to 625kHz

  • Preamp Gain: 47 dB maximum

  • Preamp Filtering: Sea State HPF and Anti-Aliasing

  • Preamp Noise: 0.7nV per root Hz RTI

  • Digitization: 24-bit differential @ fs = 1.25MHz

  • Clipping Level: >180dB re 1uPa per root Hz

  • Integrated Cyclone V SoC Processor

  • Bus Protocol: Gb Ethernet

  • Output Data Formats:

    • Raw: 24-bits

    • Compressed: 16-bit block floating point

    • DCL records

  • Power: 5 Watts maximum

  • Input Voltage: 9V to 36V Isolated Power Supply

  • Dimensions: 5" x 9" x 0.75" w/o mounting bracket

  • Weight: 2 kg (in air) w/o mounting bracket

  • Maximum Depth: 150 meters

  • Low Cost: $15K/$10K in low/medium volume

  • Optional built-in propulsion noise cancellation

  • On-Board or External Processing for:

    • Active broadband receiver

    • Passive detection of marine mammals

    • Wideband directional acoustic receiver and recorder for improved situational awareness

​

Installs on platforms without requiring recessed pressure bottle or fairing. Blade design minimizes drag, maintains laminar flow over array, and provides close to 4 Pi steradian coverage. Includes input for an external  accelerometer or hydrophone to cancel propulsion noise. This is essential for best performance in UUV applications.

Extreme Sonar Ultra-Wideband 200 Watt Pulser

​

  • Low-cost, high-efficiency, wideband Pulser based on a synchronous Class-E Power Amplifier

  • Generates positive and negative high current 200 ns impulses at voltages of up to 1.5 KV peak-peak

  • Ideal for driving acoustic projectors for:

    • Ultrasonic Antifouling,

    • Wideband Acoustic Countermeasures,

    • Bottom Profiling and Mine Hunting,

    • Ultrasonic Imaging,

    • Terrain and Obstacle Avoidance, and

    • Underwater Communications.

  • 3.375" x 2.5" x 0.625" PCB

  • Delivers 200 Watts into a piezo-ceramic transducer array from a 12V @ 20A input

  • Conduction cooling to the case through the bottom PCB layer saves space and avoids requirement for fans, heat sinks or heat pipes

  • Incorporates a waveform generator for Frequency Hopping Spread Spectrum (FHSS), arbitrary waveform generation, or external input

  • Waveform output monitor for receiver synchronization and matched filter detector

  • Low parts count and high reliability

  • Configured to work efficiently with piezoceramic transducers over a wide frequency band without requiring application specific tuning inductors

  • I2C status outputs for board temperature, voltage, current and power
