A strike scheme is presented by restricting the entry velocity , flight path angle and introducing the conception of the best attack line. Based on this scheme, a design method of reentry trajectory is proposed when the earth is assumed to be non-rotating. The method is based on the reentry with maximum left-to-drag, but a small attack angle flight phase and a terminal adjust flight phase are included in. A feasible reentry trajectory with two or three skips can be get by adjust the small attack angle flight time. Based on this trajectory, a standard trajectory considering earth rotation and practical parameters on entry point.
