Generalized resolution in radar systems

WebAt the design stage, we adopt weighted ℓ p-norm of auto- and cross-correlation sidelobes as the objective function and minimize it for a general p value, using block successive upper bound minimization (BSUM). Considering the limitation of radar amplifiers, we design unimodular sequences which make the design problem non-convex and NP-hard. WebNov 12, 2010 · A generalized adaptive subspace detector for range-Doppler spread target (RDST-GASD) in the non-Gaussian clutter is derived in this paper. The subspace model of multi-pulse wideband radar target returns is established in the frequency-slow time domain. The clutters are modeled as nonhomogeneous spherically invariant random …

WebJan 1, 2012 · Radar azimuth super-resolution is an approach that can resolve two or more targets within the same beam in the same range unit with the same hardware condition. It is a method of signal processing to realize bearing super resolution technology [ 3 ]. The paper introduces the theory of generalized inverse filtering [ 4] proposed by doctor Kong ... 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.
