Method and apparatus for detecting targets having different radar cross-sections

摘要

The target detection method according to the present invention comprises the steps of receiving a radar reflection signal, generating first analysis target data corresponding to the radar reflection signal, and a constant false alarm rate (CFAR) for the first analysis target data. ) detecting a first target using an algorithm, generating second analysis target data by removing a signal value corresponding to the first target from the first analysis target data, and adding to the second analysis target data and detecting a second target having a lower signal-to-noise ratio than the first target by using a particle filter algorithm.
