## Abstract A lowβcost homodyne Doppler radar system with 24.128 GHz phase lock loop (PLL) frequency synthesizer has been designed, fabricated, and applied in remote detection of heart beat. In this direct conversion Doppler radar system, the PLL frequency synthesizer is utilized as a highβstabilit

We show that nonadiabatic, resonant amplitude-and phase-modulated pulses can be frequency converted with greater efficiency than adiabatic resonant pulses in a double K system, interacting with two strong cw beams on one side of the system, and a weak pulsed probe on the other. Indeed, in this doubl
