Implementation of a RADAR System using MATLAB and the USRP
Radar system the software defined radio data
2014/12/31
This project report presents an approach to designing a radar system using software defined radio. The project objective was to demonstrate a SDR radar that would transmit and receive chirp waveforms....
Accuracy of Biomass and Structure Estimates from Radar and Lidar
Accuracy Biomass Interferometry Lidar Radar Structure
2014/11/7
A better understanding of ecosystem processes requires accurate estimates of forest biomass and structure on global scales. Recently, there have been demonstrations of the ability of remote sensing in...
Spaced-Antenna Wind Estimation Using an X-Baand Phased-Array Weather Radar
Pure sciences Earth sciences Wind estimation Phased-array Weather radar Signal processing
2014/11/7
Over the past few decades, several single radar methods have been developed to probe the kinematic structure of storms. All these methods trade angular-resolution to retrieve the wind-field. To date, ...
Rao statistical test for radar targets based on SG-Alpha stable distribution
radar target detection Rao test subGaussian-Alpha stable distribution non-Gaussian clutter
2012/3/22
In relative non-Gaussian clutter backgrounds, one of the difficulties on radar target detection is to establish a likelihood ratio test model. Based on the SG-Alpha（subGaussian-Alpha）stable distributi...
Target detection for CDMA based passive radar using array antenna
passive bistatic radar code division multiple access (CDMA) array antenna target detection
2012/3/22
Within a system of code division multiple access (CDMA), in an area there exist multiple base stations which transmit different signals in the same frequency bandwidth. And usually it is difficult to ...
Improved algorithm on retrieval ocean surface current based on X-band radar
ocean surface current X-band radar dispersion relationship membership least square method (LSM)
2012/3/22
In order to overcome the traditional current retrieval algorithm’s shortcomings based on X-band radar, such as a large error existing at the low current rate and the unsteady result, an improved algor...
Nonlinear scattering at HF: Prospects for exploitation in OTH radar systems
Nonlinear scattering nonlinear transfer function Volterra expansion rusty bolt HF radar OTH radar HFSWR
2010/10/12
HF skywave `over-the-horizon' radars experience exceptionally high levels of clutter from the earth's surface as a consequence of their `look-down' propagation geometry. While Doppler processing is ef...

High Frequency Surface Wave Radar HFSWR Detection Tracking Ships Maritime Domain Awareness
2010/10/12
In today's resource-driven economy, maritime nations are claiming economic borders that extend beyond the continental shelf or the 200 nautical mile (nm) Exclusive Economic Zone (EEZ). However, claimi...
Oceanography radar system WERA: features, accuracy, reliability and limitations
Radar WERA Current Waves
2010/10/12
The WERA system (WavE RAdar) is a shore based remote sensing system to monitor ocean surface currents, waves and wind direction. This long range, high resolution monitoring system based on short radio...
