Seven experts from China Institute of Metrology, Southeast University, Nanjing University of Aeronautics & Astronautics and other units formed an acceptance committee. The inspection and acceptance meeting was presided over by Zhu Jingyu, deputy researcher of the Science and Technology Department of the Planning Bureau of Jiangsu Province. Receiving experts listened to the project work report, watched the live demonstration, and after questioning and discussion, agreed that the submitted acceptance data was complete and met the requirements for the acceptance of science and technology projects, completed the project task book goals, agreed to pass the acceptance, and gave a higher evaluation.

The “Research on Calibration Technique of Low-Frequency Magnetic Field Radiation Intensity Meter” studied the measurement characteristics and calibration methods of low-frequency magnetic field measuring instruments, and developed many important components such as high-performance Helmholtz coils, current monitors, probe positioning devices, and low-frequency power amplifiers. A low-frequency magnetic field measuring instrument calibration device was realized, and the device performance was comprehensively tested and evaluated. A three-port current monitor for accurately measuring low-frequency currents was first proposed and developed in China.

The project “Research on on-site simulation method and detection device for radar speedometer for motor vehicles” analyzes the distribution characteristics of the radar speedometer beam at the installation site, and proposes a speed-measuring radar detection method for simulating real vehicle echo signals in the speed measurement area. The vehicle is designed and manufactured. The on-site detection device of radar gunometer fills the domestic gap and realizes the full-scale and high-efficiency safety detection of radar on the spot.
