Problems solved by technology

[0002] In the prior art, the entire radio frequency system will be divided into multiple independent subsystems and placed in any position due to some restrictions on the placement environment. The length of the radio frequency connecting cables is different, and the radio frequency channel Some internal channels need accurate RF signal amplitude correction. Due to the inconsistent length of RF connecting cables between subsystems, after integrating a large system, the direction finding index may be out of tolerance
Replacing the RF connection cable during maintenance may cause a large gap between the RF signal amplitude correction and the previous system. At the same time, if the internal RF channel of the subsystem is repaired and replaced, the RF signal amplitude will also be too different from the previous system. Due to the multiple independent parts The locations of the sub-systems are relatively scattered, and it is impossible to know whether the correction value of the RF signal amplitude is true and credible after the repair and replacement of any part inside the whole system.

Embodiment 2

[0046] The present embodiment makes further supplements on the basis of embodiment 1, specifically as follows:

[0047] This embodiment provides a method of combining radio frequency internal and external correction. The method provided by this embodiment further includes:

[0048] (4) Combination of internal and external correction after replacing parts:

[0049](a1) When there is a problem with the radio frequency cable or radio frequency channel part, replace the radio frequency cable or radio frequency channel part that needs to be replaced into the radio frequency system, perform internal calibration, and obtain the amplitude value table of each frequency of each radio frequency channel after replacement, and record it as No. The second internal correction configuration file is stored in the system computer board for operation, and the second internal correction fitting curve of each radio frequency channel is obtained, such as Figure 7 shown;

[0050] (a2) Equilibrium...

Abstract

The invention relates to the technical field of electronics, and discloses a radio frequency internal and external correction combined method and a computer storage medium. According to the method, before the radio frequency system is assembled in a placing environment, special radio frequency cables with the same length are used for connecting all subsystems for external correction, then after the radio frequency system is assembled in the placing environment, internal correction is carried out, and finally external correction and internal correction are combined. According to the method provided by the invention, the radio frequency system can adapt to any complex assembly environment, the authenticity of the correction value after the parts of the system are replaced can be ensured through an internal and external correction mode, and a reliable guarantee is provided for the radio frequency system to accurately receive the direction finding of an external radiation source for a long time.
