MIMO radar waveform design for transmit beampattern synthesis

2016 24th European Signal Processing Conference (EUSIPCO), 2016
In this paper, the waveform design for transmit beampattern synthesis is studied in MIMO radar systems with colocated antennas. The waveform transmitted at each antenna is defined as a weighted sum of a set of discrete prolate spheroidal (DPS) sequences which have good orthogonal and band-limited properties.

Adaptive beampattern synthesis based on null broadening

IEEE Antennas and Propagation Society Symposium, 2004., 2004
An adaptive method based on null broadening is proposed for synthesizing an array beampattern with low sidelobe levels. A number of interfering signals are assumed to be incident on the array from the sidelobe region to reduce the sidelobe levels. The weights of the beampattern are calculated based on the MVDR (minimum variance distortionless response)

Beampattern synthesis for wideband mimo radar systems

1st IEEE International Workshop on Computational Advances in Multi-Sensor Adaptive Processing, 2005., 2006
A MIMO radar system is a radar system with multiple transmitters, each driven with its own signal, coherently with all the other transmitters. In this paper we consider the problem of using this flexibility to transmit wideband signals and control the spatial distribution of transmitted power.

Beampattern-Invariant MIMO Covariance Matrices: Synthesis and Applications

IEEE Transactions on Wireless Communications
The conventional method of designing the desired beampattern in MIMO systems involves the computation of the waveform covariance and/or weight matrices. In this work, through some simple derivations, it is demonstrated that there are infinitely many covariance matrices that yield the same beampattern.

A Symmetrically Increasing Frequency Offset for Short Range Beampattern Synthesis

2019 International Conference on Communications, Signal Processing, and their Applications (ICCSPA), 2019
The frequency diverse array (FDA) has been previously proposed for long range-angle dependent beamforming. Recently, attention has shifted to the more practically feasible short range-angle transmit beamforming synthesis. In this paper, a symmetrically increasing frequency offset is introduced which generates a more compact beampattern compared to ...

Unconstrained Synthesis of Covariance Matrix for MIMO Radar Transmit Beampattern

IEEE Transactions on Signal Processing, 2011
Multiple-input multiple-output (MIMO) radars have many advantages over their phased-array counterparts: improved spatial resolution; better parametric identifiably and greater flexibility to design the transmit beampattern. The design of the transmit beampatterns generally requires the waveforms to have arbitrary auto- and cross-correlation properties.

Transmit beampattern synthesis using eigenvalue decomposition in MIMO radar

2011 8th International Conference on Information, Communications & Signal Processing, 2011
MIMO radar is the next generation radar which transmits arbitrary waveforms at each one of its apertures. It has been shown that design of waveforms for MIMO radars in order to synthesize a desired spatial beampattern is mapped into a waveform correlation matrix (R) design in the narrowband case.

Transmit beampattern synthesis for sub-arrayed MIMO radar

2012 IEEE International Conference on Signal Processing, Communication and Computing (ICSPCC 2012), 2012
Sub-arrayed multiple-input multiple-output (MIMO) radar is a new architecture of MIMO radar, which can exploit jointly the benefits of the coherent processing gain and waveform diversity, and has received extensive attention of researchers. An approach to synthesize the desired transmit beampattern for sub-arrayed MIMO radar is proposed in this paper ...

Quartic Optimization for MIMO Radar Transmit Beampattern Synthesis

2019 IEEE International Conference on Signal, Information and Data Processing (ICSIDP), 2019
This paper considers the design of multiple-input multiple-output (MIMO) radar waveforms to approximate a desired beampattern. The problem is formulated as minimizing the weighted squared-error between the synthesized beampattern and the desired beampattern, and the spacial cross-correlation sidelobes with the energy and peak-to-average ratio (PAR ...
