Images usually refer to video images which capture the density of light in each pixels. Instead of density of light, there are many other measurements we can use to sense the objects. For example, radar can sense the intensity of the reflected microwave or acoustic signal at each location. In this chapter, we review and describe new methods for using airborne beamforming radar to create images. By using radar technology, the images so created can have new information, such as velocity and distance. In this paper, we first review the characteristic of optical imaging. Then we proposed an image construction method using low cost airborne beamforming and compare the relationship between optical image and the created radar image. The performance of this method is also investigated. This kind of radar image can be used as a supplement of optical imaging to increase processing speed and accuracy.
