摘　　要：研究了航天器的比例导引交会制导规律．基于比例导引法的基本思想和交会时刻的约束条件，推导出脉冲式比例导引规律，这种导引规律较容易实现．仿真结果表明，具有较高的支会精度．his paper discusses rendezvous problems of two spacecrafts using proportional navigation.A rendezvous problem requires that the relative range and relative velocity between the two spacecrafts must be zero simultaneously at the time of rendezvous. The control of both range and velocity to realize rendezvous implies complex terminal maneuvering.The control acceleration of maneuverable spacecraft must be a resultant made up of a component along the line of sight that reduces the relative closing velocity to zero as the tWo spacecrafts approach one another and a component normal to the line or sight that will reduce the rate of line of sight to zero, i.e..will insure that the two spacecrafts approach a collision course. In the paper pulse proportional navigation law is derived using the end condition of rendezvous. Numerical computational example is given to verify the effectiveness of navigation law.
