High-precision angle estimation based on phase ambiguity resolution for high resolution radars

A High-Resolution Imaging Algorithm without Derivatives Based on Waveform Estimation for UWB Radars

UWB pulse radars enable us to measure a target location with high range-resolution, and so are applicable for measurement systems for robots and automobile. We have already proposed a robust and fast imaging algorithm with an envelope of circles, which is suitable for these applications. In this method, we determine time delays from received signals with the matched filter for a transmitted wav...

High-Resolution Angle Estimation for an Automotive FMCW Radar Sensor

This paper introduces the application of high-resolution angle estimation algorithms for a 77GHz automotive long range radar sensor. Highresolution direction of arrival (DOA) estimation is important for future safety systems. Using FMCW principle, major challenges discussed in this paper are small number of snapshots, correlation of the signals, and antenna mismatches. Simulation results allow ...

A New Structural Matching Method Based on Linear Features for High Resolution Satellite Images

  Along with commercial accessibility of high resolution satellite images in recent decades, the issue of extracting accurate 3D spatial information in many fields became the centre of attention and applications related to photogrammetry and remote sensing has increased. To extract such information, the images should be geo-referenced. The procedure of georeferencing is done in four main steps...

Ground-based Optical/Infrared Interferometry: High Resolution, High Precision Imaging

Over the past decade, optical interferometry has demonstrated that its combination of high resolution and high precision can make unique contributions to astrophysics. Interferometers have grown in aperture size, baseline length, number of apertures, and spectral resolution. At the same time, methods to circumvent the limitations of interferometry are being introduced. Further increases in sens...
