Description

technical field [0001] The invention relates to a C-band high-power ferrite fast full polarizer, which belongs to the technical field of radar polarization. Background technique [0002] Although the research on polarization information in radar echoes began in the 1950s, it has not become a hot spot. In recent decades, with the development of threats such as stealth targets, electronic jamming, classification, and target identification, the polarization information Utilization and research mentioned an important position, and became the frontier technology of the development of new radar technology. [0003] There are many ways to realize the application of variable polarization technology at present, and the ferrite variable polarization technology has always been paid attention to by people. From the mid-1980s to the mid-1990s, the single ferrite electronically controlled variable polarizer developed and designed has been successfully applied to the national "Yuanwang" a...

AI Technical Summary

Problems solved by technology

In terms of polarization switching speed, the existing polarizer has a slow polarization switching speed, the switching speed is 5-10ms, which is difficult to meet the application in continuous tracking, anti-jamming and other functions

In terms of power, due to structural reasons, the existing polarizers can withstand low power, with a peak power of 500-600kw and an average power of 1kw, which is difficult to meet various applications in high-power scenarios.
