The invention relates to a high frame frequency high precision injection star map simulation test platform based on target identification. According to the characteristics of a spaceborne identification system, a combination mode of a DSP image processing module and an FPGA image synthesis module is proposed, high-precision image sequences are obtained through image capture, image synthesis, layeroverlay and grayscale correction, in the image capture process, a representation method based on a grayscale value of a star map is proposed, star map simulation test requirements for accurate spatial target identification and tracking are guaranteed, and reliable accuracy, fast processing speed and high stability are achieved.
