Title:
AZIMUTH ESTIMATION METHOD AND AZIMUTH ESTIMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/163632
Kind Code:
A1
Abstract:
In a center generation step (S180), a center matrix, which is a correlation matrix, is generated for each peak bin extracted in an extraction step (S160), using the value of the same peak bin collected from all transmission/reception channels. In a surrounding generation step (S190), a surrounding matrix, which is a correlation matrix, is generated for each surrounding bin for each of the peak bins, using the value of the same surrounding bin collected from all transmission/reception channels. In an integration step (S200), the center matrix generated in the center generation step and one or more surrounding matrices generated in the surrounding generation step are weighted and calculated for each peak bin, and an integration matrix is generated. In an estimation step (S220), an azimuth estimation calculation is executed using the integration matrix generated in the integration step.
