Implementation of the ubiquitous radar concept with a conformal array

Abstract

Conformal arrays, distributed processors and bistatic architectures allow us to develop more and more effective phased array multifunction radars. In particular, conical (as well as cylindrical) arrays permit to avoid scan angle losses, and multiple sub-arrays with digital beamforming enhance the time-energy efficiency by executing in parallel the various radar tasks. A system architecture, now under test, is presented with some remarks about the resources management and showing the differences w.r.t. more conventional planar phased arrays (e.g. four faces). Moreover, it is shown how the operating mode can reach the one of the “ubiquitous radar” permitting virtually instantaneous detection and tracking of short-range, low-elevation targets for sea and ground point defense.
