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

Information-Theoretic Optimal Radar Waveform Design
IEEE Signal Processing Letters, 2017In this letter, we address the problem of designing the optimal radar waveform for the detection of an extended target in a colored noise environment. The locally most powerful detector and the corresponding optimal waveform based on maximizing the detector's performance under a small-signal assumption are derived.

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 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.

Detection performance is optimized and range and doppler both improved by maximizing the SNR. Since this needs the pulse to have high energy, long pulses are required unless a very high power transmitter is available. Long pulses also permit good doppler accuracy, but, for simple pulses, give poor range accuracy.

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.

Periodic Binary Waveform Design for MIMO Radar
2019 53rd Asilomar Conference on Signals, Systems, and Computers, 2019Most commercial multi-input multi-output (MIMO) radar systems, such as the increasingly popular automotive radar systems, use linear frequency modulated continuous wave (LFMCW) as probing sequences. However, mutual interference problems become increasingly severe as these radar systems become widely used.

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
