Embodiment Construction

[0041] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will facilitate further understanding of the present invention in any form of techniques, but will not limit the invention in any form. It should be noted that several variations and improvements can also be made without departing from the concept of the present invention. These are all of the scope of protection of the present invention.

[0042] The TR component is the most important component of the phase-controlled array antenna. The antenna unit is pointed to by the TR component, and the functional failure of the component will result in failure of the entire phased array antenna. The TR component cannot be quickly positioned, fault isolation, which is very inconvenient to use.

[0043] In the prior art, the present invention provides a phased array antenna TR component fault monitoring method, which may include acquiring a control code for each TR c...

Abstract

The present invention provides a phased array antenna TR component failure monitoring method and system, the method comprising: obtaining the control code of each TR component; sending the control code to the corresponding TR component according to the interface timing of the TR component; The control code written into the TR component is read back, and the control code read back is compared with the sent control code; if the comparison result is inconsistent, record the TR component as a suspicious TR component, and switch to the failure Process mode to troubleshoot the suspect TR component. The present invention can realize autonomous monitoring of TR components, discover early TR component faults, avoid phased array antenna beam pointing disorder caused by faults, and affect application operations, has high reliability, and can also realize rapid positioning of component faults, Improve fault recovery efficiency.

Description

Technical field [0001] The present invention relates to the technical field of phased array antenna, and in particular, to the phase control method and system of the phase control array antenna TR component. Background technique [0002] The TR component is an important component of the phase-controlled array antenna. There is a digital circuit and a radio frequency circuit within the TR component, where the digital circuit is used to receive the control code of the external waveguide and the exciter, which further adjusts the phase, amplitude of the radio frequency circuit portion. Due to digital circuit aging, single-particle flip (aerospace sector), etc., the dysfunction of the digital circuit part of the TR component, thereby causing the TR component radio frequency phase, amplitude error, resulting in phased array antenna beam pointing errors, affecting Rail work. In addition, the number of TR components in the active array antenna can be brought to the operation and mainten...
