Wideband waveform design for clutter suppression
2014 IEEE 8th Sensor Array and Multichannel Signal Processing Workshop (SAM), 2014Modern signal generators offer the capability to synthesize arbitrary wideband waveforms for radar and sonar applications. This makes it possible to optimize signals for specific purposes or scenarios. Herein, we discuss how to design a wideband waveform for clutter suppression.

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 ...

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.

Waveform design for QAM-FBMC systems
2017 IEEE 18th International Workshop on Signal Processing Advances in Wireless Communications (SPAWC), 2017Due to its spectral efficiency and well-localized spectrum, a quadrature amplitude modulation based filter-bank multi-carrier (QAM-FBMC) is considered as one of the candidate for 5G mobile communications. In this paper, we propose a novel waveform design for the QAM-FBMC system considering time dispersion parameter.

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.

On waveform design for optimal target discrimination
International Journal of Imaging Systems and Technology, 1992AbstractProbability theory is applied to the problem of radar target discrimination. The theory is used to construct an excitation waveform (an enhanced discrimination pulse) which maximizes the posterior odds in favor of one target over the other. It is shown that the enhanced discrimination pulse has its spectrum concentrated near the frequency where

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.

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 ...

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.
