To examine whether the effect of color categorical perception is a perceptual phenomenon,the present research adopted a modified target-detection paradigm,in which a verbal interference task was combined with a target-detection task.

Design and application of same distribution test for target detection accuracy;

Application of new texture analysis algorithm in target detection;

Design and application of target detection range related analysis;

Romote sensing technical method of wide band or high spectrum is described briefly and the research and applying status of subpixel,low probability and object detection are introduced.

Millimeter wave object detection makes use of the electromagnetic thermal emission of the subject and reflected thermal signals from the background, millimeter wave object detection, in comparison to visible or infrared object detection, has great potential advantage of detection through fog、cloud、smoke、sandstorms and other poor weather conditions.
