Title: Intruding object discrimination apparatus for discriminating intruding object based on multiple-dimensional feature

Abstract: A normalization processing circuit normalizes a position of a complex demodulation signal on a complex plane from an A/D converter, and outputs a normalized complex demodulation signal after the normalization to a multiple-dimensional feature extractor. The multiple-dimensional feature extractor calculates a feature quantity that changes when a person intrudes, a feature quantity that changes in wind and rain, and a feature quantity that changes when a spatially isolated intense electric field exists. A discriminator discriminates that a person has intruded based on the feature quantities of three dimensions.
