Reinforcement Learning For Waveform Design
2021 IEEE Radar Conference (RadarConf21), 2021In this paper we propose the use of a deep neural network (DNN) trained using deep deterministic policy gradient (DDPG) reinforcement learning (RL) to solve a simplified radar waveform design problem. The problem is to select phases for a phase-coded waveform with a power spectrum (PS) containing a low-power notch to support spectrum sharing.

Waveform design for electroseismic exploration
The Journal of the Acoustical Society of America, 2006Electroseismic (ES) exploration remotely identifies the presence of hydrocarbons using the conversion of electromagnetic energy to seismic energy. These conversions are relatively larger in a porous, permeable resistive body (such as an oil or gas reservoir) when compared with background conversions.

Introduction to waveform design
2021In this chapter, fundamental concepts are introduced for the waveform design. Generalized definition of the waveform is given to provide a basis for the discussions in the first two parts. Several relationships for the waveform design are investigated, and then application requirements of different wireless communications standards are discussed ...

Developments in radar waveform design
12th International Conference on Microwaves and Radar. MIKON-98. Conference Proceedings (IEEE Cat. No.98EX195), 2002The design of radar waveforms has made significant advances over the past two decades. This has been prompted both by increasingly stringent radar performance requirements and the development of high-speed digital processing hardware. The purpose of this paper is to review two specific examples of modern waveform design, and to attempt to make some ...

Waveform design for Commensal Radar
2015 IEEE Radar Conference (RadarCon), 2015Commensal Radar has been proposed as a means of addressing the spectrum congestion problem. It may be defined as a passive bistatic radar (PBR) in which the communications, broadcast or radionavigation waveform is designed not only so that it fulfils its primary purpose, but also so that its properties are in some sense optimized as radar signals. This

Sixth International Conference on `HF Radio Systems and Techniques', 1994
HF over-the-horizon radars often use CW transmissions comprising repeated linear FM sweeps. The resolution and sidelobe performance in the range dimension are determined within each sweep, but Doppler information is extracted by processing together the outputs of a number of sweeps.

Waveform Design with Spectral Coexistence
2019 IEEE Radar Conference (RadarConf), 2019To ensure spectral compatibility between radar and communication systems, the radar waveform design of spectrum shaping is considered. The weighted squared-error between the designed Energy Spectrum Density (ESD) and the desired ESD is developed as figure of merit to minimize.

In this chapter, we review various probing waveform transmission schemes for multiple-input multiple-output (MIMO) radar with co-located antennas. An orthogonal probing waveform set is required to separate the transmitted waveforms at the receiver side to achieve a large virtual array size afforded by the MIMO radar.
