Title:
MOVING BODY DETECTING DEVICE, MOVING BODY DETECTION SYSTEM, AND MOVING BODY DETECTION METHOD
Document Type and Number:
Japanese Patent JP2019100716
Kind Code:
A
Abstract:
To accurately detect a moving body even under environment having large disturbance.SOLUTION: A moving body detection method includes: a first process for transmitting wideband radio waves toward a predetermined detection area; a second process for calculating signal strength in each of a plurality of areas for composing the detection area on the basis of reflection waves of radio waves; a third process for locating a presence area in which a moving body exists from among a plurality of areas on the basis of a time variation in signal strength in each of a plurality of areas; and a fourth process for tracking a position of a moving body on the basis of a time variation in signal strength in each of a presence area and at least one adjacent area that is adjacent to the presence area.SELECTED DRAWING: Figure 5
