Handheld devices can scan the lower limbs of a patient and 'listen' to the blood flow, providing vital early indication of problems that could lead to strokes or heart attacks. But inexperience or ...

Thanks to MeerKat, this detection was possible. The radio telescope was able to detect the signals from the interstellar object when it was 3.76 degrees away from the Sun, almost seven times the Sun’s ...

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

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 ...

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 ...

A novel method using signals of opportunity from Low Earth Orbit (LEO) satellites is redefining what’s possible in satellite-based navigation. Researchers have developed a joint pseudo-range and ...
