Fmcw modulation scheme
WebContinuous-wave radar (CW radar) is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects. Individual objects can be detected using the Doppler effect, which causes the received signal to have a different frequency from the transmitted signal, allowing it to be … WebThe key idea of the classic FMCW modulation scheme is to transmit linear frequency ramps with different slopes as depicted in Fig. 6 (a). The transmit time is usually in the range of a couple of milliseconds and the number of transmitted ramps is limited. This realisation is also called slow ramp modulation. The transmit signal is reflected
