Webbandwidth of the 220GHz FMCW radar is 15GHz, and the output power is more than 80mW. Firstly, the range profile is achieved by performing FFT to the de-chirp data and the TP plane is achieved by performing STFT to the de-chirp data, shown in fig.3. In fig.3(a) the defocusing phenomena of the radar range profile is obvious. WebThese micro scale movements produce additional Doppler shifts, referred to as micro-Doppler effects, which are useful in identifying target features. This example shows two applications where micro-Doppler effects can be helpful. In the first application, micro-Doppler signatures are used to determine the blade speed of a helicopter.
