摘要	At the time of marine navigation for the astronautic measurement ship, it was mainly subject to radar precision appraisal through accuracy calibration flight; thus it has long period, large costs, hard organization and coordination, and other defects. By taking advantages of high-precision star sensor and radar strap-down to track and measure the space target, a kind of marine precision appraisal method was proposed. At the time of tracking space target by radar, the star sensor shoots the star map nearby the antenna pointing. Firstly, the star sensor calculated the initial pointing of the bore-sight by the angle of the encoder output by radar; through fast star map identification and target localization, the precision pointing of the geocentric coordinates system for the antenna was obtained; Then, it was transformed to the horizontal coordinate system from the coordinate; according to atmospheric refraction model, the pitch angle of the horizontal coordinate system was corrected; and it was transformed to the deck coordinate system through ship swing correction; Finally, the pointing precision evaluation of radar was realized through axial system error and miss distance correction. The experimental result shows that comparing with the star sensor, the azimuth and pitch angle random rest error of the ship-borne radar measured by using the method is superior to 50, which meets the requirement of radar precision evaluation and shows the method is feasible. 2017, Science Press.
