Moreover, since the FMCW method relies on the measurement of low-frequency signals, a sampling rate significantly reduced can be used. The development of an FMCW ultrasonic range-finder device performing most of the processing at an hardware level is therefore highly desirable. See more In order to explicitly evaluate \chi(t)and to demonstrate the efficiency of the method for ToF measurements, further mathematical details about the chirp signal must … See more The signals used in practical implementations are periodic, that is s(t)=s(t\pm nT) and y(t)=y(t\pm nT). For each period, there are therefore two distinct regions … See more In digital signal processing, the number of acquired samples is a limiting factor for the standard procedures based on the use of transforms, such as the DFT. … See more WebNov 5, 2008 · An ultrasound FMCW signal is transmitted into human tissue and the reflection signal is received after the two- way propagation time in human body.
