The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

Curtiss-Wright’s E-SOQPSK (Extensible SOQPSK) is a software-configurable, ultra-low-power Wi-Fi modulation scheme. Its waveforms offer some beneficial performance attributes for aeronautical telemetry ...

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 ...

Synthetic-aperture radar, in which a moving radar is used to simulate a very large antenna and obtain high-resolution images, is typically not the stuff of hobbyists. Nobody told that to [Henrik ...
