Exact Amplitude--Delay Information Crossover for an Idealized Helical DAS Array

Buobe IA context · why it matters

Exact finite-array frequency where amplitude and delay info match — This allows precise extraction of both types of data simultaneously.
Prespecified Hann–DFT–MUSIC chain validation — Ensures reliable bearing estimation under compatible observation conditions. Fique de olho:
Improved compatibility between array-domain and processing-chain estimates for practical DAS applications.
