Abstract: An accurate grid locking method for a target composite tracking system in a terminal area comprises a cooperative engagement processer in each platform which performs for arranging a radar data storage structure, storing the target plot data received by the cooperative engagement processer in the corresponding radar data storage structure one by one, processing target plot data of a previous sector to form a target track, distributing the obtained target track to another platform on a data link, and receiving track data of a remote target distributed by another platform, inputting the track data into the plot data storage structure of the platform.

Abstract: A camera decoration part, fabrication method, and electronic device. The camera decoration part includes a first plate and a second plate; a first surface of the first plate has a decoration rendering; a second through-hole corresponding to a first through-hole is disposed on the second plate; a first surface of the second plate includes a connection area and an avoidance area, where the avoidance area is formed by recessing the first surface of the second plate to a second surface of the second plate by a first depth, a thickness of the second plate is greater than or equal to a height of a protrusion on a housing of the electronic device, the first depth is greater than or equal to the height of the protrusion, and a projection of the protrusion is in a projection area of the avoidance area.
