摘　　要：为解决炮射高旋弹丸在弹道飞行试验中滚转角测量的参考比较问题,提出了一种基于太阳方位的弹丸滚转角估测方法。在给出了基于太阳方位的弹丸滚转角估测原理后,建立了一种视场中心角可变的太阳光可视模型,并给出了依据实际靶场射向及试验时间的光测应用方法与设计步骤,包括光测参数设计、光测时间窗口获取、滚转角估测计算及其估测误差分析。全弹道飞行试验验证了文中描述的利用太阳方位角的弹丸滚转角测量方法可行性。The roll angle estimation method based on solar azimuth is proposed to solve the problem of no references or comparisons needed for roll angle measurement of cannon-launched high-spin projectile in ballistic flight experiment.When the roll angle estimating principle based on the solar azimuth is given,a sunlight visual model with variable central angles of FOV is established,meanwhile,according to the factual launch direction and test time,the photometrical application method and design procedure are given,including photometrical parameter design,photometrical time window acquisition,roll angle estimation and estimation error analysis.It is indicated from the whole trajectory of flight experiment that the roll angle measurement methods based on the solar azimuth is feasible.
