Figure 12.

Domain highlighted in yellow where (f_h, δν_rms) satisfies the three conditions described by the relational expressions (21), (22) and (23) to achieve (S/N)_tgt = 200 at τ_e = 48.4 ns, γ = 62.5 GHz. The segment highlighted in blue is the domain extended by increasing the sweep rate to γ = 625 GHz/s. The red and blue solid lines show the boundary curves defined by δν_rms = 0.0293/f_h and δν_rms = 0.293/f_h in a log-log scale to satisfy the third expression (23) at 0.5 nm/s (= 62.5 GHz/s) and at 5 nm/s (= 625 GHz/s), respectively.
