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. WebTitle: DSTO-TN-1386.dvi Created Date: 12/19/2014 11:52:37 AM phone box types https://allcroftgroupllc.com
