Function Description

EdgeTech 4200: Advanced Side Scan Sonar System

The EdgeTech 4200 is an advanced side scan sonar system designed for marine surveys, seabed mapping, hull inspections, shipwreck exploration, and more. It delivers high-resolution sonar imagery that effectively captures detailed information on seabed topography, sediments, objects, and structures. This versatile system is ideal for applications in marine research, environmental monitoring, oil and gas exploration, and underwater archaeology.

1. Key Features

(1) High-Resolution Imaging

  • HD Side Scan Imaging: Provides high-resolution seafloor imagery for accurate scanning and analysis.

  • Supports Frequencies from 1.5 to 10 MHz: Enables optimized resolution by adjusting frequencies based on scanning depth and target range.

(2) Multi-Frequency Operation

  • Supports both single- and dual-frequency modes to balance scan depth and image resolution based on operational needs.

  • High Frequency (1.5–4 MHz): Ideal for shallow water and high-resolution imaging.

  • Low Frequency (400 kHz–1 MHz): Suitable for deeper water, expanding coverage range.

(3) Wide Scan Coverage

  • Maximum scan range up to 600 meters in shallow water, ideal for large-area seabed exploration.

  • Adjustable scan width allows for both high-resolution, narrow-range and low-resolution, wide-range scans.

(4) Low-Noise Design

  • Engineered for low-noise operation to reduce environmental interference and enhance sonar image clarity.

(5) Automatic Depth Tracking

  • Provides real-time depth feedback during scans.

  • Features auto-calibration and noise filtering to ensure stability and accuracy.

(6) Powerful Data Processing and Analysis Software

  • Equipped with advanced processing tools that support multiple data formats (e.g., XYZ point cloud, imagery, sonar data).

  • Compatible with third-party GIS and data visualization software for further analysis and mapping.

2. Main Applications

  • Seafloor Mapping and Surveying: Measures seabed shape, rocks, and sediments.

  • Marine Archaeology: Locates shipwrecks, ancient ruins, and other underwater artifacts.

  • Wreck Search and Exploration: Assists in pinpointing shipwrecks and historical objects.

  • Environmental Monitoring: Detects underwater objects and monitors ecosystems.

  • Oil and Gas Exploration: Scans underwater structures to aid in exploration and development.

  • Underwater Construction: Provides detailed seabed maps for underwater installation support.

3. System Components and Options

  • Sonar Transmitter: Sends out acoustic pulses.

  • Receiver and Data Processor: Captures echo signals and processes data.

  • Display and Control Unit: User-friendly interface for display and operational settings.

  • Optional Add-ons: Various transmitter and receiver configurations available to expand functionality and application range.
