Reconstruction of cubic and quadratic phase components of a multicomponent input signal: (a) and (b) spectrograms of the input signal in Equation (39) with Hann windows of widths 23 and 11 samples, respectively. (c-e) Bilinear TCR distribution in Equation (41) for the input signal in radian chirp-rate ranges [0, π/2], [π/2, π] and [2π, 3π], respectively. (f) Prepared TCR mask to include the ICR line with the larger positive slope in Figure 2c.
