The paper assesses the feasibility of forming a composite excitation
pulse with a high potential to combat the noise and onset ambiguity when
estimating the target resonance behaviour in a radar target signal. The
assessment investigates four composite pulse configurations of unified
or adaptive setups for the fractional bandwidth and peak weight to find
the best setup in enhancing the resonance signature robustness. The
assessment uses the method pencil function to extract the resonance
parameters of the composite time data (coherent) and then determine the
degree of robustness over-extraction onset and range of noise level.
Determining the robustness rate requires finding the error between the
original excitation frequencies and the extractable resonant frequencies
and, second, the similarity between the original and reconstructed pulse
waveforms. The qualitative assessments of the robustness merit concluded
that the adaptive configuration of peak weight and small adaptive
fractional bandwidth outperforms the other configurations in enhancing
the resonance signature robustness.
