Diving movement high squint SAR sub aperture imaging space variance correction method based on two-stage filtering

The invention belongs to the field of radar signal processing and discloses a diving movement high squint SAR sub aperture imaging space variance correction method based on two-stage filtering. An imaging geometric model is established, an original echo signal is subjected to range Fourier transform, a range walk correction and acceleration compensation function is constructed, and preprocessing is achieved. Then a compensated signal is transformed into a two-dimensional frequency domain, a first-order frequency domain filter factor is constructed to correct the space variance of a range envelope, a signal which is subjected to range direction process is transformed into an azimuth two-dimensional time domain through reverse Fourier transform, a high-order phase compensation function is constructed, then the compensated signal is transformed into an azimuth frequency domain, a second-order frequency domain filter factor is constructed to correct the space variance of azimuth Doppler parameters, a corrected signal is transformed into an azimuth time domain, and an azimuth unified compensation factor is constructed to implement the azimuth processing. Finally, a signal which is subjected to the azimuth processing passes an FFT to obtain the azimuth frequency domain to improve an azimuth focus depth.

Production method of metal etching handicraft picture

The invention discloses a production method of a metal etching handicraft picture. The production method comprises the following steps of: exposing a black and white film on a substrate coated with metal photosensitive ink, performing developing treatment, cleaning, etching and re-cleaning in sequence, performing drying, wire drawing treatment and sealing, and storing a finished product. The production method has the advantages that an etching effect is good, especially for the handicraft picture with fine etching lines, as a side protective agent is added in etching liquid, grain marks are clear and complete when the handicraft picture is etched, the phenomenon that the grain marks are unclear caused by side corrosion cannot occur, a V-shaped structure is formed at the bottom of patterns in etching, the patterns and texts which are etched in the substrate show a stereo effect, especially the texts are etched, the stereo effect is good, and the patterns and fonts cannot discolor or deform so as to be convenient to keep for a long time. The etching method disclosed by the invention can be used for ensuring an attractive effect of the product, and is high in etching efficiency which is dozens of times that of a mechanical engraving machine, so that the working efficiency is greatly improved. The production method can be widely applied in multiple industries.

Water-in-water multicolor paint preparation method capable of high-speed slicing and granulation and paint prepared by method

ActiveCN106752567AGood mechanical strength and toughnessImprove ergonomicsMulticolor effect coatingsPelletizingChemistry
The invention discloses a water-in-water multicolor paint preparation method capable of high-speed slicing and granulation. The preparation process comprises the following steps: preparing an 8% protective glue solution; 2. preparing a basic paint; 3. preparing a basic color paint; 4. preparing a multicolor particle solution; and 5. preparing the water-in-water multicolor paint finished product. After the color matching is carried out on the basic paint, the 8% protective glue solution is utilized to perform system reinforcement; and in the granulation and slicing process, the 8% protective glue solution and a hydrophobic modified anionic surfactant are premixed, so that the negative-valence ions in the anionic surfactant sufficiently capture cations on the nano modified magnesium lithium sodium silicate mineral salt molecule surface to form a series of strict film structures, thereby eliminating the risk of rejection caused by color bleeding, fusion and thickening since colored particles can not be completely coated in time. Thus, the obtained water-in-water multicolor paint has the advantages of excellent mechanical strength, excellent toughness and high spraying efficiency. The invention also discloses a composition of the water-in-water multicolor paint.

Method of protecting archives with red-ink handwriting from spreading and sinking in during process of papering and repairing

Provided is a method of protecting archives with red-ink handwriting from spreading and sinking in during process of papering and repairing. The method comprises the steps of uniformly mixing, by mass, 1 part of phospho-tungstic acid, 2.3 to 3.9 parts of phosphoric acid, 48.8 to 52.0 parts of acetone and 2.8 to 9.2 parts of tetraeththyl orthosiliate to prepare a first reinforcing agent and coating the agent on red-ink handwritings; preparing a second reinforcing agent with 1 part by mass of ethyl cellulose, 6.25 parts by mass of barium hydroxide and 40 parts by mass of methanol and coating the agent on the red-ink handwritings coated with the first reinforcing agent; and preparing a third reinforcing agent with, by mass, 1 part of ethyl cellulose banana oil solution and 0.03 to 0.17 part of polymethylmethacrylate banana oil solution, wherein mass percentage of the ethyl cellulose banana oil solution is 4% and mass percentage of the polymethylmethacrylate banana oil solution is 4%, andcoating the third reinforcing agent on the red-ink handwritings coated with the second reinforcing agent. The method of protecting the red-ink handwritings enables improvement in tensile strength, folding strength and tearability of testing paper after dry heating aging, hydrothermal aging and ultraviolet aging tests. After the aging process, the handwritings which are reinforced by the reinforcing agents exhibit minor chromatic aberration. Pigments of the handwritings are not easy to fade and the handwritings can be durably kept.
