1results about How to "Strong tracking ability" patented technology

This invention discloses an indoor target localization and trajectory tracking method and system based on millimeter-wave radar. The method includes: acquiring the frequency-modulated continuous wave emitted by the millimeter-wave radar towards the target area and receiving the echo signal; demodulating and transcoding the echo signal; performing preliminary noise reduction on the demodulated and transcoded data; segmenting and extracting the data after preliminary noise reduction to obtain a dataset; filtering environmental noise from the dataset to obtain a first-optimized dataset; clustering the first-optimized dataset to filter out noise generated by the target during movement, obtaining a second-optimized dataset; and using a constant false alarm rate (CFAR) detection algorithm on the second-optimized dataset, using peak points in the clustering results to replace the entire clustering interval to complete target localization.
