OMP-type Algorithm with Structured Sparsity Patterns for Multipath Radar Signals [PDF]
, 2011 A transmitted, unknown radar signal is observed at the receiver through more than one path in additive noise. The aim is to recover the waveform of the intercepted signal and to simultaneously estimate the direction of arrival (DOA).

Radio disturbance of high frequency surface wave radar
Electronics Letters, 2004 Based on a dual-polarisation high frequency surface wave radar system, main characteristics and performance of radio are described, and a new polarisation filter (adaptive null phase-shift polarisation (ANPSP)) is proposed. Filtering the disturbance in each pulse and keeping the original phases of the targets, more than 50 dB SIR improvement is ...

Ultra-Wide Swath SAR Imaging With Continuous PRF Variation [PDF]
, 2010 Innovative multi-channel synthetic aperture radar (SAR) concepts enable high-resolution wide-swath imaging, but the antenna length typically restricts the achievable swath width.

MIMO High Frequency Surface Wave Radar Using Sparse Frequency FMCW Signals
International Journal of Antennas and Propagation, 2017 The heavily congested radio frequency environment severely limits the signal bandwidth of the high frequency surface wave radar (HFSWR). Based on the concept of multiple-input multiple-output (MIMO) radar, we propose a MIMO sparse frequency HFSWR system ...

Mapping Shallow Water Coastal Areas Using a Standard Marine X-Band Radar [PDF]
, 2008 The bathymetry and currents in a 4km radius area of the Dee Estuary in Liverpool Bay have been mapped using a wave inversion of marine radar data without the need for any prior bathymetric data.

High frequency surface wave radar (HFSWR) simulator [PDF]
, 2019 110 p. High Frequency (HF) - Radar ,also known as Over-The-Horizon (OTH) Radar is able to detect targets that are over the horizon up to a few hundreds kilometers, beyond the range of a conventional radar. The intrinsic properties of a HF signal enable the radio frequency (RF) signal to propagate along the earth surface. MASTER OF ENGINEERING (EEE)
