Multiple input multiple output (MIMO) radar exhibits several advantages with respect to traditional radar array systems in terms of flexibility and performance. However, MIMO radar poses new challenges for both hardware design and digital processing. In particular, achieving high azimuth resolution requires a large number of transmit and receive antennas. In addition, the digital processing is ...

We present a map of the coseismic displacement field resulting from the Landers, California, June 28, 1992, earthquake derived using data acquired from an orbiting high-resolution radar system. We achieve results more accurate than previous space studies and similar in accuracy to those obtained by conventional field survey techniques. Data from the ERS 1 synthetic aperture radar instrument acq...

Basic radar systems use electromagnetic wave reflections from targets to determine the motion characteristics of these targets. Synthetic Aperture Radar (SAR) systems use the reflections to produce target images as well. SAR is an imaging radar system that produces high resolution images of a scene or target by using radar motion to synthesize the antenna aperture. A SAR model to handle extende...

This paper considers a number of aspects related to the achievement of non-cooperative target recognition capabilities in current and near-future radar systems. The scope of the paper is restricted to consideration of the use of high range-resolution profiles. Three particular aspects are discussed. Firstly, the problem of achieving a high range-resolution capability on radars which typically h...

Within framework of UKoLoS project the new Super Resolution Maximum Length Binary Sequence UWB Radar (M-sequence radar) was developed. The radar consists of an M-sequence generator, transmitter front-end, receiver front-end, data capturing device and data processing blocks, whose design responsibilities were carried out by four institutions. In this thesis the design and measurements of the dat...

This paper proposes a method for accelerating an enhanced resolution 3D (range, velocity, and azimuth) Multiple Input Output (MIMO) radar on Graphics Processing Unit (GPU). Implementation of MIMO radars the investigation their performance are interest to research community. However, mode operation increases computational requirements system seldom permits real-time without compromises. Current ...

[1] Coherent radar imaging (CRI), which is fundamentally a beamforming process, has been used to create images of microscale, reflectivity structures within the resolution volume of atmospheric Doppler radars. This powerful technique has the potential to unlock many new discoveries in atmospheric studies. The Turbulent Eddy Profiler (TEP) is a unique 915 MHz boundary layer radar consisting of a...

Synthetic aperture radar (SAR) is a general method for generating high-resolution radar maps from low-resolution aperture data which is based on using the relative motion between the radar antenna and the imaged scene. Originally conceived in the early 1950s [1], it is extensively used to image objects on the surface of the Earth and the planets [2]. A synthetic aperture is formed using electro...
