WebFeb 22, 2024 · A conceptual diagram of FMCW ladar. Often times, one desires to know the range to one or more targets along the beam path. Figure 2 shows a range profile, this … FMCW radar (Frequency-Modulated Continuous Wave radar = FMCW 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 … See more Characteristics of FMCW radar are: 1. The distance measurement is accomplished by comparing the frequency of the received signal to a reference (usually directly the transmission signal). 2. The duration of the transmitted … See more By suitable choice of the frequency deviation per unit of time can be determined the radar resolution, and by choice of the duration of the increasing of the frequency (the longer edge of the red sawtooth in Figure … See more There are several possible modulation patterns which can be used for different measurement purposes: 1. Sawtooth modulation This … See more An FMCW radar consists essentially of the transceiver and a control unit with a microprocessor. The transceiver is a compact module, and usually includes the patch antenna implemented as separate transmit and receive … See more education and obesity
