System and method for moving target detection |
摘要 |
A system and method of detecting moving targets comprises transmitting electromagnetic waves rays from a plurality of transmitters at sequential; receiving reflected waves into a plurality of receivers after each transmission; the compilation of the reflected waves from the plurality of receivers for each transmission representing a data frame; forming a signal that monitors changes between the two sets of frames; at least one processor operating to process and compare frames; forming a difference image using a back-projection algorithm; scanning the difference image using a constant false alarm rate (CFAR) window; the CFAR window scanning the entire difference image and identifying a list of points of interest and eliminating the sidelobe artifacts present in the difference image thereby creating CFAR images; processing the CFAR images using morphological processing to create a morphological image; determining the number of clusters present in the morphological image; using K-means clustering to indicate the centroid of each cluster; and tracking using a Kalman filter. The system comprises a plurality of M transmitters, a plurality of receivers, and at least one memory, the transmitters operating in sequence to transmit electromagnetic waves rays sequentially; the receivers receiving reflected waves after each transmission; the compilation of the reflected waves from the plurality of receivers for each transmission representing a data frame; at least one processor operating to perform the method.
