Building High-Performance Radar Signal Transceiver Systems with RF SoC Technology
Addressing Multi-Channel, High-Speed, and Synchronization Challenges
The high-performance radar signal transceiver system integrates high-speed signal acquisition, synchronized transmission, large-capacity data storage, and real-time processing capabilities, working in conjunction with modular hardware architecture and software platforms, to meet the demands for high-precision perception of complex environmental targets in fields such as aerospace exploration and meteorological monitoring.
PART.01
Core Hardware Platform
The system operates through RF SoC RF transceiver modules, high-precision clock sources, high-speed signal storage recorders, and gigabit industrial switches, which work together to support the system’s requirements for high-speed signal acquisition, synchronization, and large-capacity data storage:
RF SoC RF Transceiver Module:
The core hardware of the module is the QT2347DR RF transceiver card, which is responsible for the RF transceiver and signal processing functions of the system.
· Multi-Channel:The single board provides 8-channel signal acquisition and transmission capabilities. The system integrates two QT2347DR RF transceivers to achieve 16 channels of high-speed signal acquisition and multi-channel signal transmission.
· High Speed:Frequency coverage from 5M to 6GHz, supporting a maximum 1.6GS/s signal acquisition rate and 3.2GS/s signal transmission rate, meeting the needs for broadband high-speed signal processing.
· Flexible Interfaces:Onboard are 2 QSFP28 type 100Gb high-speed optical interfaces, one M.2 type SATA interface, one SD card, and equipped with 26 general-purpose GPIOs for precise triggering (3 channels), inter-device communication (6 channels), and complex logic control, enhancing the adaptability of the entire signal acquisition system.
High-Precision Clock Source:
This unit supports an external high-stability clock, providing the system with a phase-aligned 100MHz clock source and external synchronization source, ensuring phase synchronization across multiple devices, with clock jitter controlled to <100ps, guaranteeing precise synchronization of signal acquisition and transmission.
High-Speed Signal Storage Recorder:
Two QTC4000 units are responsible for data storage and forwarding, communicating with the QT2347DR via QSFP28 optical ports, supporting a maximum storage capacity of 8TB, with a storage bandwidth of 3.2GB/s, and data export using a gigabit Ethernet interface with RJ45, exporting at 70MB/s.
8-Port Gigabit Industrial Switch:
Connects 2 QT2347DRs and 2 QTC4000s, enabling internal device management and data exchange, and provides one gigabit electrical port for communication with the host computer.
PART.02
Software and Logic Platform
Logic Algorithms:
Data buffering and extraction algorithms are used to optimize processing flows and reduce real-time display load.
Software Control:
QT SDR Host Software implements parameter configuration (triggering, acquisition, transmission), system monitoring, and 16-channel waveform synchronized dynamic display, visually presenting acquisition results.
PART.03
Integrated Chassis Design
Hardware is highly integrated into a 4U chassis (width 482.6mm x height 177mm x depth 550mm, air-cooled), with rich interfaces and optimized layout.
The radar transceiver system developed by Kunqi Technology achieves high-speed signal acquisition, synchronized transmission, long-duration large-capacity data storage, and real-time processing core functionalities. With excellent performance, the system demonstrates significant application value in aerospace radar target detection and meteorological radar signal analysis, while also accumulating valuable technical experience and engineering practice foundations.
