Cylindrical Array Radar: Comparison to Multi-Faced Systems for Horizon Surveillance and Application to Ubiquitous Radar

Cylindrical phased arrays are an attractive aperture for radar applications due to their steering-angle independent gain, beamwidth, polarization, sidelobe levels, and reflection coefficient. Moreover, the ease with which they form omnidirectional and wide–sector–covering transmit beams facilitates ubiquitous radar – allowing the ability to simultaneously see everywhere. The reduced scan time of ubiquitous radar, however, is coupled with an increased dwell time to maintain constant range.
