Abstract: In applications where large time-bandwidth products and high target speeds combine, linear FM pulse-compression systems used in radar or sonar suffer considerable losses in performance. This ...

Abstract: A new in-phase/quadrature (I/Q) complex modulation technique to realize single-sideband time-modulated phase only weighting on an array antenna is proposed. Based on modulating rectangular ...

After 30 years of refinements, mud-pulse systems transmit data more quickly and more accurately, through increasingly deep wellbores. Operators are pushing telemetry systems to transmit real-time data ...

New urban heartbeat: Scientists have created the 'Urban Pulse' system to monitor neighborhood-level construction and infrastructure activity in near real time using satellite imagery. Patterns in ...
