Editor to share with you what dbf refers to the file format, I hope you will learn something after reading this article, let's discuss it together!

Dbf is a special file format, which represents the database files generated by database files, Foxbase,Dbase,Visual FoxPro and other database processing systems. Digital beamforming technology is the product of the combination of antenna beamforming principle and digital signal processing technology, which is widely used in the field of array signal processing.

Dbf is a special file format, which represents the database files generated by database processing systems such as Foxbase,Dbase,Visual FoxPro.

The abbreviation of dbf,Digital Beam Forming, translated as digital beamforming or digital beamforming, also represents a database file. Digital beamforming technology is the product of the combination of antenna beamforming principle and digital signal processing technology, which is widely used in the field of array signal processing.

Extended data:

Digital beamforming (Digital Beam Forming,DBF) technology is aimed at the array antenna, which uses the aperture of the array antenna to form a receiving beam in the desired direction through digital signal processing.

Although the pattern of a single antenna is omni-directional, for the signals of multiple receiving channels of the array, the digital processing method is used to compensate the phase difference caused by the propagation path difference caused by the different spatial position of the sensor, so as to realize the in-phase superposition, so as to realize the maximum energy reception in this direction and complete the beamforming in this direction to receive the useful desired signal.

This aggregates the directional gain received by the array in a specified direction, which is equivalent to forming a "beam". By changing the weight, the beam can be pointed in different directions and the beam can be scanned. Through multi-channel parallel processing, multiple beams can be formed at the same time, and the appropriate window function can be selected to reduce the sidelobe level.

DBF technology belongs to array signal processing, which has been widely used in radar, electronic reconnaissance and electronic countermeasure, communication, sonar and other fields.
