動体検知装置
Document Type and Number:
Japanese Patent JP6386410
Kind Code:
B2
Abstract:
The invention relates to a moving object detection apparatus. Provided is technology for improving determination accuracy of whether there is a moving object. According to a transmitted wave (VT) and a combined wave of transmitted waves (VR) on a plurality of reflecting objects (300), a generation part (17) generate an amplitude relative to the value of a variable x, as which a distance to the moving object detection apparatus is set and a phase change complex signal that is a determination function. The determination function is a combined signal of multiple independent complex signals corresponding to the plurality of reflecting objects (300). Each independent complex signal is changed according to a differential distance of the distance between the variable x to corresponding reflecting object (300) of the independent complex signal. A moving object detection part (111) gets a differential vector of a second complex plane vector representing time change of a first complex plane vector and a third complex plane vector representing an moving affect containing a non-detected object in the time change, and whether there is a moving object is judged according to the differential vector.
