The proposed structure utilizes the extended two-level nested array (ENA) as transmitter and receiver and adjusts the interelement spacing of the receiver with an expanding factor. By optimizing the array …
Weband resolution, the beamwidth, and ultimately the spatial resolution, of a system is a direct function of the signal wavelength. For example, for a 3-cm RADAR system with a 1-m antenna, t = 0.03 rad (1.72 deg); and for a 1.06-μm LADAR with a 50-mm (2 in) aperture, t = .000021 rad (only 0.0012 deg). WebAug 25, 2024 · With the development of science technology, especially the stealth technique, hypersonic aircraft, high-precision tracking, and high-resolution imaging quality [1,2,3], radar high-speed maneuvering target detection and localization has been receiving a growing attention and significant research efforts in the airborne, spaceborne, …
WebFor a given wavelength, the longer the antenna, the higher the spatial resolution. From a satellite in space operating at a wavelength of about 5 cm (C-band radar), in order to get a spatial resolution of 10 m, you would need a radar antenna about 4,250 m long. (That's over 47 football fields!)
