Ke Ji Ri Bao·2025-11-07 13:31Core Viewpoint - China Railway Signal & Communication Corporation (CRSC) has developed the CRSC-RD-5 micro-target detection radar, which has received national certification, indicating its compliance with national standards for radio frequency emission and electromagnetic compatibility, thus enabling its large-scale deployment across the country [1][3]. Group 1: Technical Achievements - The CRSC-RD-5 radar can detect micro unmanned aerial vehicles (UAVs) with a radar cross-section (RCS) of only 0.01 m² at a distance of 5 km, showcasing its high detection capability [1]. - The radar features a flexible search mode that allows for 360° omnidirectional coverage and precise domain control, and it can simultaneously track four targets, enhancing its performance in complex scenarios [1][3]. - The radar's measurement accuracy in direction and distance has reached industry-leading levels, providing precise data support for low-altitude security [1]. Group 2: Innovation and Technology - The radar's innovation is based on three core technologies: - Transmit-receive isolation technology, which reduces crosstalk noise and enhances sensitivity for low RCS target detection [3]. - Low-cost multi-channel technology, which achieves high cost-performance for parallel target detection through integrated design and simplified calibration [3]. - Sub-array grouping processing technology, which improves response speed and resource utilization by enabling collaborative operation of sub-arrays [3]. Group 3: Market Impact and Applications - The successful industrialization of the radar establishes a milestone in the industry by creating a complete industrial chain of "hardware + software + solutions," expanding into emerging markets beyond rail transportation [5]. - Pilot applications have been successfully conducted in regions such as Xiong'an New Area, Chongqing, and Qingdao, with plans for further promotion and adaptation to critical security needs in airports and nuclear power plants [5].
