IPC: G01S13/46
Filed: 2022-02-25
Abstract: The present invention relates to a system of Internet-of-Things (IoT) passive radar stations consisting of multiple passive radar stations connected via a wireless two-way radio link to the Internet. The system would be employed for locating and monitoring objects of natural or anthropogenic origin in the atmosphere, in outer space or on the ground surface as well as objects in water bodies. Applications include remote sensing of the Earth’s ionosphere from the ground, tracking celestial bodies and artificial satellites of the Earth, control of airspace and aquatic areas, monitoring of vehicle traffic and so forth. The advantages of the present invention stem from the integration of modules for two-way wireless radio communication with the Internet in passive radar stations which creates a system of passive radar IoT stations and thereby leads to better quality of the monitoring data and to more extensive spatial coverage of the system. For the system of IoT passive radar stations to be able to operate, a wireless network to the Internet (1) is required so that the wireless two-way radio communication modules (21 ... 2N) can connect to the Internet. Each module is controlled by a corresponding passive radar station (31 ... 3N). The deployment of the stations at different locations increases the space covered by the system and ensures that the system can operate even if one or more stations fail as a result of damage or external impact. Each station connects to the others via the established radio link over the Internet and exchanges with them data related to the monitoring carried out. As a result, a three-dimensional image of the monitored space is visualized.
