摘要：
A system for detecting ice accretion includes a probe body, at least one magnetostrictive guided wave sensor for generating and receiving shear horizontal-type guided waves supported by said probe body, and a controller. The magnetostrictive guided wave sensor includes a ferromagnetic strip, at least one sensor coil disposed adjacent to said ferromagnetic strip, and at least one biasing magnet configured to induce a biasing magnetic field in said ferromagnetic strip. The controller includes a processor in signal communication with the at least one magnetostrictive guided wave sensor. The processor configured to cause the at least one magnetostrictive guided wave sensor to generate guided waves in the body, extract at least one signal feature from a guided wave signal received by the at least one magnetostrictive guided wave sensor, and determine at least one characteristic of ice accreted on an outer surface of said probe body.
