The Design and Implementation of Multi-radar Signal-level Cooperative Detection System

Distributed multi-radar cooperative detection can effectively detect stealth targets based on backscattering characteristics, and with the rapid development of communication and computing technology, signal-level fusion will become the development trend of multi-radar data fusion in future. Multi-radar signal-level cooperative detection technology is systematically studied in this paper. The concept, system composition, and work flow of multi-radar signal-level cooperative detection is given, and the realization process of signal-level cooperative detection and anti-jamming technology is researched. A cooperative detection test system consisting of 5 radars was constructed to test the feasibility of multi-radar signal-level cooperative detection and anti-jamming technology, and the test results show that, compared with single radar detection, the performance of multi-radar signal-level cooperative detection is greatly improved.
