Detection false alarm suppression method based on multi-directional difference residual energy correlation

The invention discloses a detection false alarm suppression method based on multi-directional difference residual energy correlation. According to the characteristics of background clutter energy characterizing instability under different registration accuracies, false alarm target distinguishing is carried out: multi-directional difference and residual energy distribution correlation calculationare carried out for a suspected target area, and fast and effective distinguishing of a false alarm target is realized through the energy distribution change situation of a multi-directional difference image. For the false alarm target, the higher the registration accuracy, the smaller the residual energy of the differential image; and the lower the registration accuracy, the larger the residual energy of the differential image. For real moving targets, the residual energy distribution of differential images under different registration accuracies is almost unchanged. Through adoption of the multi-directional differen
