MIMO Radar Imaging Method with Non-Orthogonal Waveforms Based on Deep Learning

open access: yesAlgorithms, 2022
Transmitting orthogonal waveforms are the basis for giving full play to the advantages of MIMO radar imaging technology, but the commonly used waveforms with the same frequency cannot meet the orthogonality requirement, resulting in serious coupling ...

Comparison of Radar Receivers for OFDM and OTFS waveforms

open access: yes, 2023
9396A generic description for common multi-carrier radar receivers is proposed. Two multi-carrier waveforms - orthogonal frequency division multiplexing (OFDM) and orthogonal time-frequency spacing (OTFS) - which could be used for joint radar and ...

MIMO Dual-Functional Radar-Communication Waveform Design With Peak Average Power Ratio Constraint

open access: yesIEEE Access, 2021
In this paper, novel Dual-Functional Radar-Communication (DFRC) waveforms with peak average power ratio (PAPR) constraint are designed, which are under the multiple-input multiple-output (MIMO) radar-communication system.

Reduction of sidelobe levels in multicarrier radar signals via the fusion of hill patterns and geometric progression

open access: yesETRI Journal, 2021
Multi‐carrier waveforms have several advantages over single‐carrier waveforms for radar communication. Employing multi‐carrier complementary phase‐coded (MCPC) waveforms in radar applications has recently attracted significant attention.

The Determination of Effective Beamwidth of Ku Band Profiling Radar Based on Waveform Matching Method in the Boreal Forest of Finland

open access: yesRemote Sensing, 2020
Radar scientists typically define the radar beamwidth as a half-power beamwidth (HPBW) in the main lobe of the antenna pattern. However, the microwave radiations outside radar HPBW might also backscatter into the radar receiver and change the ...

Adaptive optimization technology of segmented reconstruction signal based on genetic algorithm for enhancing radar jamming effect

open access: yesFrontiers in Physics, 2023
Given the improved capabilities of radar systems, addressing unfamiliar signals presents a challenge for radar jamming technology. To tackle this issue, this study proposes an adaptive technique for optimizing jamming waveforms to suppress multiple false

Parameter estimation for peaky altimetric waveforms [PDF]

open access: yes, 2013
Much attention has been recently devoted to the analysis of coastal altimetric waveforms. When approaching the coast, altimetric waveforms are sometimes corrupted by peaks caused by high reflective areas inside the illuminated land surfaces or by the ...

Modeling Envisat RA-2 waveforms in the coastal zone: case-study of calm water contamination [PDF]

open access: yes, 2010
Radar altimeters have so far had limited use in the coastal zone, the area with most societal impact. This is due to both lack of, or insufficient accuracy in the necessary corrections, and more complicated altimeter signals. This paper examines waveform

Neural Networks for Radar Waveform Recognition [PDF]

open access: yesSymmetry, 2017
For passive radar detection system, radar waveform recognition is an important research area. In this paper, we explore an automatic radar waveform recognition system to detect, track and locate the low probability of intercept (LPI) radars. The system can classify (but not identify) 12 kinds of signals, including binary phase shift keying (BPSK ...
