| Abstract: | Because of the single directionality of the strong beam and the uniform distribution energy of the weak target, it is feasible for the detection of the weak image the strong beam disturbance. In the detection of the weak target image, the background is regarded as a kind of texture and the existence of the weak target changes the local textural features. To use the multiple correlation analysis for getting textural features, we can detect the weak target image. The multiple correlation analysis is also used for judging whether the image filtering is going on or not. It has been proved as an effective detection means in the experiments. |
