The frequency-modulated interrupted continuous waveform (FMICW) has been widely used in remotely sensing sea surface states by high-frequency ground wave radar (HFGWR). However, the cross section model of for this not yet presented. Therefore, first- and second-order models about are derived study. derivation begins with general electric field equations. Subsequently, FMICW source is introduced...

In this paper, a hybrid 2D-Measurement technique is presented for the estimation of the remote position of an active reflector unit (Tag), in terms of radial distance and azimuth angle. The technique is based on Interferometry and FMCW multistatic radar system which operates in the European UWB frequency band [6-8.5 GHz]. The measurements have been performed in a real indoor environment for the...

In this paper, a 24 GHz direct conversion receiver (DCR) for frequency-modulated continuous-wave (FMCW) ranging radar based on low flicker noise mixer in 90 nm silicon-on-insulator (SOI) CMOS technology is presented. A low-noise and low-power low-noise-amplifier (LNA) adopting simultaneous input matching (SNIM) method designed. Neutralized boost inductor are introduced to improve performance. T...

This paper formulates a novel fast three-dimensional joint superresolution algorithm for millimeter wave (mmWave) imaging. The existing techniques estimation are inherently slow. Firstly, the size of correlation matrix, used subspace-based algorithms such as MUltiple SIgnal Classification (MUSIC), increases with dimension. escalates computational cost singular value decomposition (SVD) or eigen...

We present the design of a novel K-band radar architecture for short-range target detection. Applications include direction finding systems and automotive radar. The developed system is compact low cost employs substrate-integrated-waveguide (SIW) antenna arrays 4×4 Butler matrix (BM) beamformer. In particular, proposed transmits frequency modulated continuous-wave (FMCW) signal at 24 GHz, scan...
