This dataset is primarily intended for calibration research on reflection coefficients of common terahertz building materials. It is generated via calibrated measurements on a channel detection platform based on the principle of time-domain spread-spectrum sliding correlation. The platform consists of two parts: a transmitter (Tx) and a receiver (Rx). The transmitter comprises a signal generator R&R®SMW200A, RF cables, frequency conversion modules, and a power amplifier. The signal generator of the transmitter generates a FZC sequence with excellent autocorrelation characteristics as the detection signal, which is up-converted to a terahertz signal with a local oscillator signal through the frequency conversion modules, and radiated to the outside via an antenna. The receiver is composed of a low-noise amplifier, frequency conversion modules, a spectrum analyzer, and a control computer. The receiver captures the received signal, which passes through the low-noise amplifier, then is down-converted to an intermediate frequency (IF) signal with a local oscillator signal in the frequency conversion modules, and finally fed into the signal and spectrum analyzer R&S®FSW43. The main recorded data are the real-time collected time-domain in-phase and quadrature (IQ) dual-channel data acquired by the spectrum analyzer. The total data volume is 3.94 MB.
