False target suppression method, system and device based on wide-spectrum characteristics and medium

The invention discloses a false target suppression method, system and device based on wide spectrum characteristics and a medium, and the method comprises the steps: S1, carrying out the adaptive broadband compensation of a received echo signal, and carrying out the threshold detection after the superposition of multi-point scattering peak values is completed; s2, after the target is detected, extracting response characteristics corresponding to the statistical target, and judging the authenticity of the target; and S3, carrying out statistics on the characteristics of the detected target, and when the detected target is set as a real target or a false target twice or more, outputting a judgment result of the detected target as a detection result. According to the method, the real target and the false target are identified by using the difference between the wide-spectrum response characteristic of the target and the false target characteristic generated by the interference signal, so that the false target is
