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.

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 ...

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.

Discrete Frequency-Coding Waveform Design
2007 14th IEEE International Conference on Electronics, Circuits and Systems, 2007A modified simulated annealing algorithm (MSAA) is proposed to design discrete frequency-coding (DFC) sequence sets with good autocorrelation and crosscorrelation properties. The proposed algorithm is a combination of simulated annealing and Hamming scan algorithm.

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.

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.
