WebJul 4, 2011 · These results are then related to the standard definition of linearity. Measurements from a commercial VCO are finally used to convincingly validate the work, resulting in a simple and practical method to predict the impact of source nonlinearity, as defined by the FSV parameter, on the performance of an FMCW radar system. WebThe invention relates to an FMCW sensor, generating a send signal on the basis of a high frequency from a frequency oscillator (FFO) and a modulated low frequency (mod(t)) from a second oscillator (VCO). The modulated frequency is converted into a reference signal (ref(t)) in a delay line with a surface wave element (SAW).
