LF-500

LF-500

The LF-500 is a comprehensive low-frequency sonar testing system that simulates and validates active and passive sonar performance under real marine conditions. It collects critical data, such as reverberation, ambient noise, sound speed, and depth, while evaluating self-noise from both sonar systems and vessels. The system calculates key acoustic parameters, including attenuation and reflection losses, and supports active and passive calibration for transmitter power, frequency, and receiver sensitivity, enabling precise, mission-ready performance validation and modeling.

Features
  • Emulate target movement with Doppler shift, up to ±30 knots.
  • Transmits from 300 Hz to 50 kHz; receives from 300 Hz to 80 kHz.
  • Creates Sine, AM, and FM sonar pulse types.
  • Operates down to 200 meters via a 250-meter cable and winch.
  • Provides GPS for geo-referenced data and outputs audio in .wav format.
  • Includes ray-tracing and broadband shallow water simulations.
  • Determines Probability of Detection (PoD) and minimum detection range.
  • Compares simulations to real-world measurements for performance validation.
  • Uses buoy-based sensors for continuous environmental data.
  • Features 16 channels at 512 ksps each.
  • Supports VHF, cellular, wired, and underwater modem links.
  • Calibrated with seabed geoacoustic signals, supports low/medium frequency sonar (150 Hz – 60 kHz).
