Radar waveform design for detection of weapons
2010 2nd International Workshop on Cognitive Information Processing, 2010We present waveform design based on signature exploitation techniques for improved detection of weapons in urban sensing applications. We consider a single-antenna monostatic radar system. Under the assumption of exact knowledge of the target orientation and, hence, known impulse response, matched illumination approach is used for optimal target ...

Optimal waveform design for cognitive radar
2008 42nd Asilomar Conference on Signals, Systems and Computers, 2008A key component of a cognitive radar system is the method by which the transmitted waveform is adapted in response to information regarding the radar environment. The goal of such adaptation methods is to provide a flexible framework that can synthesize waveforms that provide different tradeoffs between a variety of performance objectives, and can do ...

Waveforms design for modern and MIMO radar
Eurocon 2013, 2013One of the main focus of the research in modern radar systems, as MIMO (Multiple Input Multiple Output) radar and multifunction/multistatic radar, is the waveforms design and optimization in order to get a low degradation in the main lobe (low Signal to Noise Ratio loss), a low Peak Side-Lobe Ratio (PSLR) and good orthogonality properties.

Wideband MIMO Radar Waveform Design
IEEE Transactions on Signal Processing, 2019We consider the design of wideband multiple-input multiple-output (MIMO) radar waveforms to approximate a desired beampattern and achieve prescribed space-frequency nulling in a space-frequency region of interest. A general design model involving modulus, power, and energy constraints on the probing waveforms is introduced.

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 ...

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.

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.
