Xidian’s self-developed marine navigation radar was successfully applied

China News Service, Xi'an, November 7 (Reporter Alina) reporter learned from Xi'an University of Electronic Science and Technology on the 7th that the marine navigation radar independently developed by the Information Perception Integration Research Institute of Xi'an University of Electronic Science and Technology (hereinafter referred to as the Institute) has recently successfully completed a real-ship test on the Hangzhou-Ningbo Canal 1,000-ton new energy cargo ship "Zhigeji 001". During the test, the radar operated stably and detected accurately. It can clearly identify and continuously track targets such as channel shorelines, buoys, and ships. Its comprehensive performance has been fully recognized by shipyard users.

According to reports, marine navigation radar is an important guarantee for the safe navigation of water vessels. The core difficulties in applying navigation radar to small and medium-sized civilian ships are high performance, high reliability and low cost.

Inland waterways have many curves, high ship density, and complex working conditions, which impose strict requirements on the environmental adaptability and detection stability of navigation sensing equipment. Based on the real application needs of the shipping industry, the institute aims at the existing shortcomings and technical bottlenecks in environmental perception of inland river ships, continues to carry out theoretical research, prototype development and actual ship testing, and has in-depth cooperation with enterprises in the industries such as Changchun Electronics and Xiangyang Technology. It lasted more than three years to integrate and tackle key problems and break through low-cost Using core technologies such as radio frequency circuit and signal processing circuit optimization and low-complexity signal processing algorithms, we have developed a low-cost, intelligent marine navigation radar with high performance. Its functions and indicators have reached the technical level of similar foreign products, and it successfully obtained the marine product type approval certificate earlier this year.

This marine navigation radar adopts a frequency modulated continuous wave system. The workflow is mainly divided into seven links: signal transmission, echo reception, frequency mixing processing, spectrum analysis, distance measurement, position display and automatic switching. Compared with traditional pulse radar, this radar has many revolutionary advantages such as "excellent short-range detection capability, extremely high distance resolution, low transmit power and high safety, all-solid-state design and high reliability, and excellent anti-interference ability", and can be applied to various types of inland rivers, lakes and coastal small and medium-sized ships. At the same time, its subsequent derivative radar products can be widely used in shipping ship management, waterway monitoring, ship radar data services and other fields.

It is understood that this radar is a domestically produced solid-state radar. Key components such as core components and signal processing algorithms are fully autonomous and controllable, and a number of relevant patents have been applied for. The product is expected to break the long-term monopoly of foreign brands in the marine radar market, provide a stable, reliable and cost-effective domestic alternative for the ship supporting field, continue to consolidate the foundation of independent navigation sensing equipment for inland river ships, build a solid defense line for the water transportation industry chain supply chain and shipping operation safety, and provide strong support for the development of China's "maritime power" and "intelligent shipping".

At present, the institute is working with enterprises to promote market expansion, deeply explore the application scenarios of small and medium-sized ships in inland rivers and offshore waters, continue to iteratively optimize radar performance based on feedback from real ships, steadily polish the pedigree of domestic ship sensing equipment, and use autonomous and controllable radar and multi-source fusion sensing technology to help the high-quality development of China's intelligent shipping.
