Active Phased Array Antenna Self-diagnosis Repair Device

Abstract

The invention discloses a self-diagnosing and repairing device for an active phased array antenna. The self-diagnosing and repairing of the electrical performance of the active phased array antenna can be realized by using the invention, and the monitoring efficiency is significantly improved. The present invention is realized through the following scheme: in the transmitting state, the radio frequency signal enters the silicon chip assembly, the low frequency signal enters the control repair module, and the calculated amplitude / phase code is sent to the silicon chip assembly to complete the spatial power synthesis of the radio frequency signal; state, the control repair module sends the calculated amplitude / phase code to the silicon chip component, and the radio frequency signal is amplified and phase-shifted and enters the power distribution and synthesis network module to receive; in the receiving / transmitting state, the control repair module adopts the modulus AD The chip performs digital sampling, diagnoses faults in the working state through the FPGA chip, and when the active phased array antenna stops working, activates the refresh control circuit to automatically start the active phased array antenna and perform active phased array antenna work State refresh and self-healing.

Description

technical field [0001] The invention relates to an active phased array antenna self-diagnosis repair device in the field of electronic technology. Background technique [0002] With the deteriorating electromagnetic environment of radar and the increasing number of radiating units, phased array antennas, as the core transceiver devices of wireless communication systems, will inevitably fail TR components, wave controllers, or radiating units during their daily work. The phenomenon. How to measure the radiation characteristics of the phased array antenna and use a certain fault diagnosis method to locate the specific location of the faulty unit and determine the type of fault, and then provide effective guidance for subsequent decision-making and maintenance. The testing and diagnosis technology of the phased array antenna An urgent need has been put forward, and it is still a relatively complicated technical problem. Usually, the number of components of modern large-scale ...
