Interferometer direction finding offers high precision and rapid response, making it widely applicable in passive detection and positioning systems. Traditional interferometers utilize short baselines to ensure unambiguous direction-finding range and long baselines to guarantee accuracy, typically employing integer baseline ratios. However, this method faces implementation challenges in broadband applications and exhibits high sensitivity to antenna array placement. This research focuses on fractional-order interferometer direction-finding algorithms that simultaneously achieve broadband operation, high precision, and ambiguity resolution. The study investigates the impact of different fractional ratios and phase measurement errors on direction-finding accuracy, supported by simulation-based verification.

The PSO Particle Swarm Optimization Toolbox provides an implementation of Particle Swarm Optimization (PSO), a modern evolutionary algorithm (EA) that mimics social behavior to solve optimization problems. Unlike genetic algorithms, PSO eliminates crossover and mutation operations by following the best-known solutions, enabling efficient global optimization through swarm intelligence with simple parameter tuning and rapid convergence.
