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 … See more An FMCW radar consists essentially of the transceiver and a control unit with a microprocessor. The transceiver is a compact module, … See more There are several possible modulation patterns which can be used for different measurement purposes: 1. Sawtooth modulation This … See more WebThe signals can then be recovered and processed to form the virtual array. Using the same system configuration as in previous sections, one phase-coded scheme to achieve orthogonality is to have one element always transmit the same FMCW waveform, while the second transmit element reverses the phase of the FMCW waveform for each sweep.
