Title:
電波発信源位置推定システム及び電波発信源位置推定方法
Document Type and Number:
Japanese Patent JP7279801
Kind Code:
B2
Abstract:
The present invention includes: a learning data generation unit (53) that acquires an expected value of a measured value of received power; a spatial distribution synthesis unit (54) that calculates an expected value of a measured value of received power when a radio wave is transmitted from any position in a target area; a likelihood calculation unit (55) that calculates a likelihood distribution that a radio wave source exists at each point of the target area; a position estimation unit (56) that estimates transmission power of a transmission source to be estimated, estimates a likelihood distribution at the transmission power, and estimates a position of the transmission source; and a display unit (57) that displays a spatial distribution of a conformity degree in the target area and a position of a maximum likelihood value and a position of a local maximum value of the likelihood calculated (55).
