Signal wave ratio
WebFor example, if the message signal maximum amplitude is 2 volts and carrier signal maximum amplitude is 4 volts, then the ratio of modulating signal amplitude (2 volts) to the carrier signal amplitude (4 volts) is equal to 0.5. Therefore, the modulation index in under-modulation is less than one (M i < 1). WebThis article investigates whether a vortex wave detection method with a rotational antenna can improve the receiving signal-to-noise ratio (SNR) of stealth targets. To be specific, a vortex wave detection system with a rotational antenna is established. Considering both bistatic and monostatic models, it demonstrates that the vortex wave can be efficiently …
