On waveform design for MIMO radar with matrix completion

2014 IEEE Global Conference on Signal and Information Processing (GlobalSIP), 2014
In matrix completion based MIMO radars, the data matrix coherence, and consequently the performance of matrix completion depend on the transmit waveforms. It was recently shown that for uniform linear arrays and orthogonal waveforms, the optimal choice for waveforms are white-noise type functions.

Optimal and robust waveform design for MIMO radars

2009 IEEE International Conference on Acoustics, Speech and Signal Processing, 2009
Waveform design for Target identification and classification in MIMO radar systems has been studied in several recent works. While the previous works considered signal independent noise, here we extend the results to the case where signal-dependent noise, clutter, is also present and then we find the optimum waveform for several estimators differing in

Waveform Design for MIMO Radars With Matrix Completion

IEEE Journal of Selected Topics in Signal Processing, 2015
It was recently shown that MIMO radars with sparse sensing and matrix completion (MC) can significantly reduce the volume of data required by MIMO radars for accurate target detection and estimation. In MIMO-MC radars, the subsampled target returns are forwarded by the receive antennas to a fusion center, partially filling a matrix, referred to as the ...

Classical radar waveform design

2012
The waveform determines the delay-Doppler response of a radar system. From that response, one can derive the radar's range and velocity resolution and their ambiguities. This chapter explains the concept and motivation for pulse compression. It then describes narrow-band signals and their major signal processing and analysis tools - the matched filter ...

Waveform design for compressively sampled ultrawideband radar

Journal of Electronic Imaging, 2013
Compressive sensing makes it possible to recover sparse target scenes from under-sampled measurements when uncorrelated random-noise waveforms are used as probing signals. The mathematical theory behind this assertion is based on the fact that Toeplitz and circulant random matrices generated from independent identically distributed (i.i.d) Gaussian ...

Joint automotive radar-communications waveform design

2017 IEEE 28th Annual International Symposium on Personal, Indoor, and Mobile Radio Communications (PIMRC), 2017
The paper studies the problem of waveform design for a joint Radar-Communications (RadComms) system in an automotive setting characterized by a multitarget environment. The envisaged joint waveform allows exploitation of existing infrastructure to support additional functionalities.

Optimal Radar Waveform Design

2014
Abstract A confluence of steady advances in radar enabling technologies, and ever increasing demands on radar performance in challenging environments, has afforded a re-examination of the fundamental theoretical framework upon which classical waveform design is based.

Minimax Robust MIMO Radar Waveform Design

IEEE Journal of Selected Topics in Signal Processing, 2007
We consider the problem of minimax robust waveform design for multiple-input multiple-output (MIMO) radar based on mutual information (MI) and minimum mean-square error (MMSE) estimation for target identification and classification. Recognizing that a single, precise characterization of target power spectral density (PSD) is rare in practice, we assume

On the design of optimum radar waveforms for clutter rejection

IEEE Transactions on Information Theory, 1967
The problem to be considered in this paper is that of designing radar signals and receivers that are optimum for detecting a point target masked by a background of clutter returns and thermal noise. The problem of choosing an optimum signal when no constraints are placed on the type of signals allowed is discussed briefly, but the remainder of the ...
