Waveform Design for MIMO Radars With Matrix Completion
IEEE Journal of Selected Topics in Signal Processing, 2015It 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
2012The 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, 2013Compressive 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), 2017The 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.

Minimax Robust MIMO Radar Waveform Design
IEEE Journal of Selected Topics in Signal Processing, 2007We 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, 1967The 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 ...

MIMO Radar Waveform Design in the Presence of Clutter
IEEE Transactions on Aerospace and Electronic Systems, 2011Waveform design for target identification and classification in multiple-input multiple-output (MIMO) radar systems has been studied in several recent works. In previous works, optimal signals for an estimation algorithm are found assuming that only signal- independent noise exists. This work extends previous research by studying the case where clutter

Reduced PMEPR Multicarrier Radar Waveform Design
2019 53rd Asilomar Conference on Signals, Systems, and Computers, 2019Multicarrier radar waveforms have many desirable properties for many radar applications. The well known multifrequency complementary phase-coded (MCPC) radar waveforms based on the consecutive ordered cyclic shift (COCS) design can achieve a low peak-to-mean envelope power ratio (PMEPR).
