Impairments Module
==================

.. module:: phased_array.impairments
   :synopsis: Realistic impairment models for phased arrays

The impairments module provides functions to model real-world effects that
degrade phased array performance, including mutual coupling, phase quantization,
element failures, and scan blindness.

Phase Quantization
------------------

.. autofunction:: phased_array.quantize_phase

.. autofunction:: phased_array.quantization_rms_error

.. autofunction:: phased_array.quantization_sidelobe_increase
