LGPR 3D Three-dimensional Array Radar System
The 3D Array Radar System data collection system includes a radar antenna array, a GNSS (GLONASS/GPS) precision positioning system, a control unit, and a mobile road laboratory
The equipment simultaneously collects both 3D radar images of the underground environment and their coordinates, integrating them into a single data array
The system is capable of conducting comprehensive road surveys with continuous coverage of the surveyed area and detecting hidden defects within the structure
Using the 3D Array Radar System, engineers can analyze and determine the location, morphology, and hazard level of each underground anomaly based on radar image cross-sections from different angles
Технические преимущества LGPR 3D
- Continuous coverage of the surveyed area, leaving no blind spots when performing multiple passes over the surveyed area
- High data collection speed and effective defect detection inside roads thanks to continuous coverage of the space under the antenna array with the emitted signal
- 3D visualization of the underground space, providing intuitive images of the internal structure for interpretation
- High integration of all equipment components. The main components, such as the control unit and antenna array, are compact in size and highly energy efficient. Attachments are easy, reliable, convenient, and quickly assembled and disassembled
- Universal external interfaces: WLAN, power supply, satellite receiver, and simultaneous configuration of multiple interfaces (interface range). The processing computer is a compact laptop, minimizing the number of wired connections
- MIMO Array Antenna Design technology supports truly big data, real-time 3D visualization, and facilitates interpretation
The arrangement of elements in the 3D array radar antenna array is based on the MIMO architecture, which ensures a high density of detected signals and a detailed radar image of the internal structure of roads
Configuration of 3D Array Radar System data acquisition profiles: high density of received data in both longitudinal and transverse directions, even in the space between the receiving and transmitting antenna elements
