Title:
レーダ信号処理器、レーダセンサシステム及び信号処理方法
Document Type and Number:
Japanese Patent JP6995258
Kind Code:
B2
Abstract:
A radar signal processing device includes: a frequency analysis unit performing frequency analysis on a reception signal of at least one reception channel generated by a sensor unit; a target object discriminating unit calculating, on the basis of the frequency analysis, a measurement value of at least one type of feature amounts that characterizes a state of a target object moving in an observation space; and a learned data storing unit storing at least one learned data set that defines a probability distribution in which the at least one types of feature amounts is measured when a recognition targets is observed in the observation space. The target object discriminating unit calculates a posterior probability that a target object belongs to each of class(es) from the measurement value using a learned data set and discriminates the target object on the basis of the calculated posterior probability.
