Antenna Pattern of Phased Array (Chebyshev Weighting)

In clutter simulation, accurately modeling the antenna pattern of phased arrays employing Chebyshev weighting constitutes a critical step. The precision of this simulation directly impacts whether the simulated clutter can faithfully replicate real-world clutter environments. Therefore, during clutter simulation, it is essential to ensure high-fidelity pattern modeling through proper implementation of Chebyshev weighting algorithms. This involves calculating array weights using Chebyshev polynomials to maintain specified side lobe suppression while preserving main beam characteristics. Such accurate simulation enables closer alignment with real-world scenarios, thereby facilitating more reliable clutter environment assessment and system performance validation. Key implementation aspects include element spacing configuration, weighting coefficient generation via Chebyshev recursion relations, and pattern synthesis through vector superposition of radiating elements.
