Description

Bijaya Kumar Muni leads a 2026 signal processing paper on estimating the direction of arriving signals, a task used in radar, sonar, and wireless networks. The classic MUSIC algorithm locates signal sources precisely but falters in chaotic, noisy, or highly correlated conditions. The authors set out to harden it.

Their method adds a robust cost function, Tukey Biweight, which down-weights wild data points, and models chaotic signal behavior with a Chebyshev-based generator. Monte Carlo simulations, repeated random trials, compared four variants. The combined chaotic and robust version consistently gave the best accuracy and resolution, especially at low signal-to-noise ratios and high signal correlation. The authors propose it for practical wireless and radar systems.
