Robust waveform design for MIMO radars
2010 IEEE International Symposium on Information Theory, 2010The problem of robust waveform design for multiple-input, multiple-output radars equipped with widely-spaced antennas is addressed here. Robust design is needed as a number of parameters are unknown, e.g., the target scattering covariance matrix and, possibly, the clutter covariance matrix.

Radar waveform design in active communications channel
2013 Asilomar Conference on Signals, Systems and Computers, 2013In this paper, we investigate spectrally adaptive radar transmit waveform design and its effects on an active communication system. We specifically look at waveform design for point targets. The transmit waveform is optimized by accounting for the modulation spectrum of the communication system while trying to efficiently use the remaining spectrum ...

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

Optimal sequential waveform design for cognitive radar
2012 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2012This paper addresses the problem of adaptive sequential waveform design for system parameter estimation. This problem arises in several applications such as radar, sonar, or tomography. In the proposed technique, the transmit/input signal waveform is optimally determined at each step, based on the measurements in the previous steps.

Unitary design of radar waveform diversity sets
Digital Signal Processing, 2008In this work, multiple radar waveforms are simultaneously transmitted, emitted from different ldquovirtualrdquo antennas. The goal is to process the returns in such a way that the overall ambiguity function is a sum of ambiguity functions better approximating the desired thumbtack shape.

Cognitive radar waveform design for spectral compatibility
2016 Sensor Signal Processing for Defence (SSPD), 2016Radar performance is strongly dependent on the transmitted waveform and its parameters which must be adapted to the surrounding environment, radar mission, goal, and task. Waveform diversity is a relatively new paradigm involving a continuous variation and adaptation of the transmitted signal to dynamically optimize the radar performance and fulfill ...

Waveform Design for MIMO Radars
IEEE Transactions on Aerospace and Electronic Systems, 2007We consider the problem of waveform design for multiple input/multiple output (MIMO) radars, where the transmit waveforms are adjusted based on target and clutter statistics. A model for the radar returns which incorporates the transmit waveforms is developed. The target detection problem is formulated for that model.

Waveform design for TDM-MIMO radar systems
Signal Processing, 2020Abstract In this paper, we propose an efficient algorithm based on second order cone programming (SOCP) to design waveform for time-division-multiplexing (TDM) multiple-input-multiple-output(MIMO) radar systems. To this end, we optimize Peak Sidelobe Level (PSL) of the transmit sequence with constant modulus constraint.

Optimal radar waveform design for moving target
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016Radar performance improvement through waveform optimization has been an ongoing topic of research recent years. In this paper, we use the optimal waveform design method to deal with the moving target in the clutter and noise. Neyman-Pearson detector criterion is used to maximize the probability of target detection. The optimal waveform is then designed
