Shared aperture jamming
Webb1 mars 2013 · This study describes the design of a wideband, low-profile shared aperture antenna operating at P-band and Ku-band. This antenna operates with dual-linear polarisation in P-band and single-linear polarisation in Ku-band. In this antenna design, it consists of one P-band microstrip patch antenna and an 8 × 8 Ku-band aperture-coupled … WebbNikon AF-S DX 18-55mm lens.The issue was the zoom was stuck on the 55mm setting, it turned out the metal rails had bent due to the fall impact on the edge of...

WebbJamming of synthetic aperture radar (SAR) is more difficult than the conventional radars because of its high processing gain. The defocusing of fake or virtual scatterers is the main problem that any jamming technique needs to tackle. An algorithm based on fractional Fourier transform is proposed for the efficient jamming of SAR. WebbThere are apertures distributed over the platform that point forward and aft, right and left, as well as up and down. Some apertures will be shared for communications, radio …
