Continuous wave 4D millimeter wave radar multi-target measurement method and system

The invention provides a continuous wave 4D millimeter wave radar multi-target measurement method and a continuous wave 4D millimeter wave radar multi-target measurement system, and relates to a radar detection technology, in particular to a continuous wave 4D millimeter wave radar multi-target measurement technology. Determining a first probability density function when the original echo signal meets a first hypothesis condition and a second probability density function when the original echo signal meets a second hypothesis condition, and filtering interference signals in the original echo signal according to a preset detection threshold function by combining the first probability density function and the second probability density function to obtain a target echo signal; obtaining a clustering center of the point cloud set based on the point cloud set corresponding to the target echo signal, and forming a clustering cluster according to the clustering center and points in the point cloud set; and according
