Adaptable Bandwidth for Harmonic Step-Frequency Radar

Figure 5

Power spectrum and range resolution of the received signals in collected by the harmonic step-frequency radar measurement system.

(a) The green plot is the power spectrum of the measured received signals when the DUT is present. The blue plot is the power spectrum of the measured received signals when the DUT is not present

(b) Normalized range profile of the received signals. The range profile is estimated using the IFFT with zero padding and the Blackman-Harris Window function
