WEST LAFAYETTE, Ind. — Doppler radar improves lives by peeking inside air masses to predict the weather. A Purdue University team is using similar technology to look inside living cells, introducing a ...

A research team has developed an extrapolation-based Doppler resolution enhancement algorithm for frequency modulated ...

Though Doppler seems relatively simple to implement in ultrasound, analog performance in the latest systems has much higher, more-difficult-to-achieve specifications than standard black-and-white ...

Developers of diagnostic-ultrasound machines must carefully consider these devices’ design and their intended applications, making trade-offs among such factors as SNR (signal-to-noise ratio), channel ...
