摘　　要：针对一般导引律在载机远距引导中存在的问题,结合远距引导的需求,设计了远距引导的三维变结构导引律。该导引律具有较强自适应性,可以使载机以期望的进入角接近目标。仿真结果表明,载机在该导引律作用下,能以较小过载,平滑轨迹快速接近机动目标,并保证载机引导结束时占有有利的空中战术态势。A three-dimensional guidance low based on variable structure has been designed according to the requirement of long-distance navigation, which can lead the attackers to the target with the desired entrance angle self-adaptively. Simulation results show that the attackers can approach the targets quickly even if the targets maneuver acutely with the minor nor- mal acceleration and smoothing trajectory, and can keep its tactical advantages at the ending of navigation.
