Tianwen Electromagnetic Signal Simulation and Development System
The Tianwen Electromagnetic Signal Simulation and Development System (Tianwen VIEW) is built upon an open Software-Defined Radio (SDR) architecture, designed as a heterogeneous platform for waveform development and simulation testing in electromagnetic signal domains including communications, radar, navigation, and electronic warfare. Targeting foreign 'bottleneck' software such as MATLAB and LabVIEW, Tianwen VIEW aims to achieve domestic substitution and extended optimization in selected application areas. It features fully independent intellectual property rights and supports domestic CPUs—including Phytium, Hygon, Sunway, and LoongArch—as well as domestic operating systems such as Kylin and UnionTech. Developed under the principle of 'one runtime environment, one interface standard, one component library', the system provides three-tier simulation capabilities—algorithm-level, equipment-level, and scenario-level—and offers advantages including scalable system architecture, high-efficiency hardware platform adaptation, and seamless integration of virtual and physical environments.
Tianwen Cloud Teaching and Experiment System
The Tianwen Cloud Teaching and Experiment System is a comprehensive, networked teaching and experimentation platform featuring hybrid virtual-physical operation, multi-purpose integration, reconfigurability, and upgradability. It supports the construction of diverse communication and electronic information laboratories in higher education institutions, and also serves as a virtual experimentation platform for remote simulation-based experiments. The software system adopts an open Software-Defined Radio (SDR) architecture developed in-house, implementing key core technologies including Web-based visual flowgraph construction, remote waveform execution control, remote waveform display, remote audio streaming, and custom component development. Additional capabilities include hierarchical user management, course management, experiment management, automated lab report generation, and waveform execution status monitoring and management. The system is fully independently developed and possesses complete intellectual property rights.
Cloud-Based Teaching Signal Simulation Server
The Cloud Teaching Signal Simulation Server uses a rack-mounted server with flexible configuration and comes pre-installed with a customized operating system and the Tianwen Cloud Teaching Lab Software.
Tiangang Electromagnetic Signal Simulation Equipment (Portable)
This device is developed based on Software-Defined Radio (SDR) technology and can simulate signals from multiple domains—including communications, navigation, radar, and electronic warfare—while supporting multi-unit networked coordination and control. Multiple devices can transmit waveforms of different signal types at varying times and frequencies, thereby constructing a multi-dimensional complex electromagnetic environment across space, time, and frequency domains. It also features electromagnetic signal reception and real-time electromagnetic spectrum visualization and evaluation. Advantages include high signal fidelity, operational flexibility, reduced equipment variety, and rapid system upgrades—making it an effective technical solution for constructing complex electromagnetic environments and related training. The Portable Type I model adopts an integrated hardware design in a ruggedized laptop form factor, with waterproof, dustproof, and shock-resistant sealed enclosure. Its spectrum coverage spans 1 MHz to 6 GHz, with a maximum instantaneous bandwidth of 40 MHz—meeting outdoor and mobile operational requirements. It is suitable for diverse applications including teaching, scientific research, and training in both laboratory and challenging outdoor environments.
Tiangang Electromagnetic Signal Simulation Equipment (Educational Standard Model)
This device is developed based on Software-Defined Radio (SDR) technology and can simulate signals from various systems including communications, navigation, radar, and electronic warfare. It supports multi-unit networked coordination and control: multiple devices transmit waveforms of different signal types at different times and frequencies, thereby constructing multi-dimensional complex electromagnetic environment spectrum signals in space, time, and frequency domains. It also features electromagnetic signal reception and electromagnetic spectrum visualization and evaluation capabilities. Advantages include high signal fidelity, operational flexibility, reduced equipment variety, and rapid system upgrades—making it an effective technical solution for constructing complex electromagnetic environment spectra and related training.
Standard Software-Defined Radio Module
The standard Software-Defined Radio (SDR) module RF210 is designed to match the functionality of the USRP B210. It features a matte-finish, shock-resistant aluminum alloy enclosure and extends the original B210’s capabilities and performance. The RF210H/G variant extends frequency coverage to 1 MHz–6 GHz. It is built around the Xilinx Kintex-7 XC7K325T FPGA and Analog Devices’ AD9361 RFIC chip, and provides both the USRP Hardware Driver (UHD) and software drivers. The AD9361 transceiver in the RF front-end delivers 40 MHz instantaneous bandwidth; combined with external up/down-conversion and filter banks, it achieves full 1 MHz–6 GHz coverage. Optimized software drivers further enable fast frequency hopping.
