Webb27 juli 2024 · An important problem is how to generate false moving targets, whose relocated azimuth position is similar to that of real moving targets. To solve this problem, an interrupted sampling scattered wave deception jamming method against three-channel synthetic aperture radar ground moving target indication (SAR GMTI) is proposed. A … Webb7 mars 2024 · Glue the two pieces of the lens cap together. Add the lens cap to the camera. It can be attached with hook-and-loop, tape or jammed into the aperture. Jamming it in place is not recommended for field cameras as it can damage the foil, but does work for practice assembly. Insert film into holders, load camera and shoot to your heart’s …
