Phased-MIMO Radar: A Tradeoff Between Phased-Array and MIMO Radars [PDF]

open access: yes, 2009
We propose a new technique for multiple-input multiple-output (MIMO) radar with colocated antennas which we call phased-MIMO radar. The new technique enjoys the advantages of MIMO radar without sacrificing the main advantage of phased-array radar which ...

Group-Theoretic Wideband Radar Waveform Design

open access: yes2022 IEEE International Symposium on Information Theory (ISIT), 2022
We investigate the theory of affine groups in the context of designing radar waveforms that obey the desired wideband ambiguity function (WAF). The WAF is obtained by correlating the signal with its time-dilated, Doppler-shifted, and delayed replicas. We consider the WAF definition as a coefficient function of the unitary representation of the group $a\

Transmitted Waveform Design Based on Iterative Methods

open access: yesJournal of Applied Mathematics, 2013
In intelligent radar, it is an important problem for the transmitted waveform to adapt to the environment in which radar works. In this paper, we propose mutual information model of adaptive waveform design, which can convert the problem of adaptive ...

Multi-Target Robust Waveform Design Based on Harmonic Variance and Mutual Information

open access: yesAdvances in Mathematical Physics, 2020
Cognitive radar is an intelligent radar system, and adaptive waveform design is one of the core problems in cognitive radar research. In the previous studies, it is assumed that the prior information of the target is known, and the definition of target ...

Pareto-optimal radar waveform design

open access: yesIET Radar, Sonar & Navigation, 2010
This paper deals with the problem of Pareto-optimal waveform design in the presence of colored Gaussian noise, under a similarity and an energy constraint. At the design stage, we determine the optimal radar code according to the following criterion: joint constrained maximization of the detection probability and constrained minimization of the Cramer ...
