Adaptable Bandwidth for Harmonic Step-Frequency Radar

Figure 6

Power spectra of the narrowband RFI. The blue line shows the target response (displayed for comparison with RFI). The red line shows the RFI. The green line is overlaid onto the red line and indicates the subband selected by the SS-MO technique.

(a) RFI input power: −95 dBm

(b) RFI input power: −85 dBm

(c) RFI input power: −80 dBm

(d) RFI input power: −75 dBm

(e) RFI input power: −70 dBm

(f) RFI input power: −65 dBm

(g) RFI input power: −60 dBm

(h) RFI input power: −55 dBm
