Protection method for satellite borne phased array TR (Transmitter/Receiver) component single event upset

Abstract

The invention provides a protection method for satellite borne phased array TR (Transmitter / Receiver) component single event upset. The method comprises the following specific process that: S1: a wave control system carries out calculation to obtain the state data of each register of the TR component, carrying out odd verifying coding, and the coded data is sent to the TR component; S2: a register odd verifying module arranged in the TR component carries out the odd verifying on the received data; and S3: when the wave control system detects that a verifying result output by the certain TR component is wrong, current work is immediately interrupted, an emergency data anomaly maintenance mechanism is started, i.e., the wave control system schedules resources to immediately calculate and configure failed TR component register data. The method owns a capability of automatically monitoring the single event upset, can automatically trigger superior equipment (wave control system) to refresh the TR component, so that the refreshing strategy of the superior equipment (wave control system) is more flexible, and pertinence is higher.

Description

technical field [0001] The invention relates to a single-event overturn protection method for a space-borne phased array TR component, and belongs to the technical field of space-borne phased array antennas. technical background [0002] Single event upset is the effect of charged particle radiation on logic devices and logic circuits. When a single space high-energy charged particle bombards the chip of a microelectronic device in a large-scale or ultra-large-scale integrated circuit, it will cause a transient logic error or hard error in the logic device or circuit, such as the flipping of the data stored in the memory cell ("1" flipping to "0" or "0" turns to "1"), resulting in data processing errors, circuit logic function confusion, etc. The phased array antenna controls the register data in the TR component through the beam control system to achieve different beam orientations. If the register data in the TR component flips, it will cause the phased array antenna beam...

AI Technical Summary

Problems solved by technology

Since the phased array TR components often contain tens of thousands of register data, the use of triple-mode redundancy measures will increase a huge number of registers in the TR components, which not only increases the development cost of the phased array antenna, but also affects the phased array antenna. The volume, weight, and power consumption of the array antenna have a very bad impact, which is very unfavorable for spaceborne applications; since the beam direction of the phased array antenna will change in real time, the timing refresh chip inside the TR component needs to have the ability to quickly store a large amount of configuration data. Not only will the internal circuit design of the TR component be extremely complicated, but the anti-single event design of the timing refresh chip itself is also very complicated, which is not conducive to spaceborne applications.
