Search-free direction-of-arrival estimation for transmit beamspace multiple-input multiple-output radar via tensor modelling and polynomial rooting

期刊: IET RADAR SONAR AND NAVIGATION, 2021; 15 (6)

In order to improve the accuracy and resolution for transmit beamspace (TB) multiple-input multiple-output (MIMO) radar, a search-free direction-of-ar......

Time reversal detection in a multistatic radar system with a varying environment

期刊: IET RADAR SONAR AND NAVIGATION, 2021; 15 (7)

Multistatic radar has the advantage of spatial diversity, but its detection performance is decreased in dense multipath scattering environments. This ......

Fast ISAR imaging method for complex manoeuvring target based on local polynomial transform-fast chirp Fourier transform

期刊: IET RADAR SONAR AND NAVIGATION, 2021; 15 (6)

In ISAR imaging, echo signals of complex manoeuvring targets have to be modelled as multi-component cubic phase signals (m-CPS). In this condition, th......

Method for functional state recognition of multifunction radars based on recurrent neural networks

期刊: IET RADAR SONAR AND NAVIGATION, 2021; 15 (7)
