Product mildew detection system and detection method based on microwave moisture instrument

The invention discloses a product mildew detection system and a detection method based on a microwave moisture instrument. The detection system comprises a microwave signal feature acquisition unit, wherein the microwave signal feature acquisition unit is used for obtaining microwave signal features according to microwave signals obtained by the microwave moisture instrument; a generalized squared-distance computing unit between a product to be identified and a mildew sample, wherein the generalized squared-distance computing unit between a product to be identified and the mildew sample is connected to the microwave signal feature acquisition unit, and is used for calculating the generalized squared-distance between the product to be identified and the mildew sample based on the microwave signal features of the product to be identified and the mildew sample; a generalized squared-distance computing unit between the product to be identified and a non-mildew sample. Whether a product is mouldy or not can be fas
