Abstract: Noncontact vital sign sensing usually utilizes highly sensitive Doppler radars. Self-injection-locked (SIL) radars have been studied to have better sensing capabilities than traditional ...

Abstract: Synthetic Aperture Radar (SAR) systems are increasingly vulnerable to Radio Frequency Interference (RFI), creating a demand for advanced detection and mitigation strategies in complex ...

Quantum radar is an emerging technology that exploits the strange phenomenon of quantum entanglement to detect objects that would be invisible to conventional radar systems. By sending out pairs of ...

I designed the circuit in Figure 1 as a part of a data transmission system that has a carrier frequency of 400 kHz using on-off keying (OOK) modulation. I needed to detect the presence of the carrier ...

As part of its unprovoked invasion, Russia has been firing massed waves of drones and missiles into Ukraine for years, though the tempo has been raised dramatically in recent months. Barrages of ...
