A kind of millimeter wave broadband system for recognizing and tracking the sea fleet targets quickly

As the traditional radar system can't quickly and effectively identify group targets, this paper uses a millimeter-wave radar system to identify, sort and track the sea fleet targets. The radar scans the sea surface firstly to get the DBS image, then the image is processed by the CFAR processor to detect the fleet targets, and finally according to various parameters provided by the INS (inertial navigation system), the positional relationship between the radar and a specific target can be worked out. Then the radar will set the servo system so that the antenna can beam the targets area and then the radar can go to monopulse tracking quickly. The results show that: the system and algorithm proposed by this paper can identify and sort the group targets and track the specific target quickly and steadily. It is suitable for the airborne or missile fields.
