Pulse compression is an important technology in modern radar system, which promotes the developments of modern radar technologies towards higher speed and ranging accuracy. The FMCW signals, with the ...

Since the conception of the laser frequency comb in the late 1990s, it has revolutionized the precise measurement of frequency and time. Beyond their initial use in optical clocks and precision ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...
