To measure the attack angle of flying object, combined with theory of slit photography and double linear CCD intersection technology, a new method based on double sequence line-array image analysis was presented, and recognition algorithm of valid data on object axis was studied. The scale matching problem in two direction of attack angle was resolved, and a measurement system was designed. Practical attack-angle measurement proves the feasibility of the proposed method. The attack angle of flying object with the ratio of length(mm) to velocity(m/s) exceeding 0.3 can be measured by the system developed in this paper.
