| 摘 要： | 简述了弹载星敏感器几种应用方案的原理,从视场大小、导航星等、观星方式、像元分辨率、三轴姿态精度、动态性能、惯性基准误差分离等方面分析、比较了各种方案的优缺点.除平台方案外,捷联星图方案和单(双)星方案的技术参数相当,动态性能均有待提高.星图方案较单(双)星方案在2个方面占优势:一是星图方案不要求调整星敏感器光轴对准导航星,星跟踪算法等技术能快速识别星图；二是星图方案可同时、连续观测6～8颗星,解算出弹体三轴姿态,可以采用先进的滤波技术准确地分离惯性基准误差.

| Abstract: | The principle of representative projects of star sensor applied in missile is simply stated.Advantage and disadvantage is discussed on FOV(field of view) size,magnitude of navigation star,resolving capability of pixel,precision of 3 axes attitude,dynamic ability,estimate the error of INS.The main parameters SMP(of star map project) and SDP(single or double stars project) are almost the same.SMP is more excellent than SDP in two aspects.Firstly,SMP needs not adjust bore sight of sensor to aim at the navigation star,and may quickly identify stars by the algorithm of star track.Secondly,SMP is able to identify 6~8 stars at one time,to obtain 3 axes attitude of the missile,and adopt advanced filter to separate the error of INS. |
