Distributed coherent aperture radar (DCAR) can realise N3 times signal-to-noise ratio promotion, as well as achieve high accuracy angle estimation since it has an equivalent large aperture. However, due to its sparse array, grating lobes are emerged in antenna pattern, which will lead to ambiguous angle estimation. Based on the various degrees of freedom of DCAR, this study proposes a multi-scale...
In distributed coherent aperture radar which is a new technology to replace traditional large aperture radars for next generation radar, all transmitted signals of unit radars should arrive at target at the same time and with the same phase so that the energy of all unit radars could be combined coherently. Therefore, the estimation of phase difference between signals at target is a key issue. In...
The distributed coherent aperture radar as a new radar technology is expected to be the next generation radar, which is much easier to transport and less expensive than traditional large aperture radar. However, the time synchronization and phase synchronization between unit radars are key issues to realize the full coherence for wideband distributed coherent aperture radar. Therefore, the time synchronization...
The distributed coherent aperture radar consists of several cooperating small aperture radars and a control center, which is proposed as a new technology to replace traditional large aperture radars for the next generation radar. The coherent performance of distributed coherent aperture radar is mainly affected by time synchronization. However, current time synchronization technology could not meet...
