Ambiguity function and imaging performance of coded FMCW

WebFMCW radar is a special type of radar sensor which radiates continuous transmission power like a simple continuous wave radar (CW-Radar). In contrast to this CW radar FMCW radar can change its operating frequency during the measurement: that is, the transmission signal is modulated in frequency (or in phase). Possibilities of Radar WebThe complex envelope of a linear FM pulse waveform with increasing instantaneous frequency is: x ˜ ( t) = a ( t) e j π ( β / τ) t 2. where β is the bandwidth and τ is the pulse duration.
