Microwave remote sensing polarization wire grid winding frame

Abstract

The invention relates to a microwave remote sensing polarization wire grid winding frame, which belongs to the technical field of aerospace remote sensing parts processing. It mainly realizes the fixation and support of the wire-wound racket, and realizes the angle positioning of the wire-wound racket through the liner, offsets the helix angle when the wire grid is wound, and satisfies the grid spacing required by different specifications of the polarized wire grid. The left and right vertical plates are overlapped with the upper and lower channel steels respectively to form a rectangular frame, and the left and right vertical plates are not connected with flanges; the upper and lower channel steels are fixedly connected with nylon rods respectively, and the guide shaft is connected to the left , Between the right vertical plate; the linear bearing is sleeved on the guide shaft to slide freely, and the two ends of the linear bearing are provided with fixing rings to position it, the liner is fixed on the linear bearing, and the winding racket is installed on the liner. The advantage is that it changes the current status of relying on imports of polarized wire grids, fills the gap in the automatic manufacture of polarized wire grids in China, facilitates the rapid installation and positioning of polarized wire grid winding rackets of different specifications, and improves work efficiency.

Description

technical field [0001] The invention relates to the technical field of aerospace remote sensing parts processing, in particular to a microwave remote sensing polarization wire grid winding frame, which is suitable for automatic winding processing of polarization wire grids of various specifications. Background technique [0002] Microwave radiometer is a microwave remote sensor that passively receives radiation signals from objects. It is playing an important role in atmospheric water vapor detection, ocean wind field detection, land resource detection, military detection and daily life. The microwave radiometer first needs to measure the two parameters of vertically polarized radiation brightness and horizontally polarized radiation brightness temperature of the target microwave radiation, and then data inversion can be performed. In order to obtain the brightness temperature of vertically and horizontally polarized radiation, a polarizer has to be used to separate the pola...

Problems solved by technology

[0003] At present, most of the polarized wire grids used in my country are imported polarized wire grids, which are expensive; while the domestic processing method of wire grids is mainly manual winding, with low precision and long production cycle

At the same time, winding machines at home and abroad are mainly used in textile wiring, electronic components, wire cutting, etc., the control variables are relatively single, and the accuracy is relatively low
