Passive source localization technology (contact email: meddut@dlut.edu.cn)
I. Product and Technology Introduction:
Based on the principle of TDOA (time difference of arrival) estimation and advanced digital signal processing technology, the time difference between the received signals is estimated and measured, and then the location of the unknown signal source is determined. The signal source to be located may be a wireless source, a (super) acoustic source, or other vibration source. This technique belongs to passive positioning and does not require the cooperation between the detector and the signal source.
Ii. Scope of application:
In radio signal monitoring and management, it can be used to locate illegal radio signal sources. In the underground pipeline leakage detection, it can be used to locate the leakage point, such as oil pipeline leakage point, water pipeline leakage point. It can also be used for underwater sound source localization.
Production conditions: The required equipment are: signal sensor, signal amplification and acquisition device, synchronization device, digital signal processing module.
Iii. Intellectual property rights, such as patents
It is planning to apply for a patent.
Iv. Scale and Investment:
The most important investment is in electronic components and manufacturing, which can be completed by one person with a college degree or above in electronic information. Investments range from thousands of yuan to nearly 100,000 yuan. Small investment, high efficiency, fast recovery.
Degree of industrialization: 1. Laboratory stage
V. Degree of technology provision and mode of cooperation:
Provide all hardware design, software design and training personnel required for the complete technology.
Vi. Market and Benefits:
There is a demand for passive positioning technology in various fields of civil and military, and in principle this technology can be used.
