Abstract

In this paper, based on the characteristics of proportional navigation, a composite guidance law is proposed for impact angle control of passive homing missiles maintaining the lock-on condition of the seeker. The proposed law is composed of two guidance commands: the first command is to keep the look angle constant after converging to the specific look angle of the seeker, and the second is to impact the target with terminal angle constraint and is implemented after satisfying the specific line of sight(LOS) angle. Because the proposed law considers the seeker's filed-of-view(FOV) and acceleration limits simultaneously and requires neither time-to-go estimation nor relative range information, it can be easily applied to passive homing missiles. The performance and characteristics of the proposed law are investigated through nonlinear simulations with various engagement conditions.

본 논문에서는 비례항법 유도의 특성을 이용하여 수동 호밍 유도탄을 위해 탐색기의 lock-on 조건을 유지하면서 충돌각 제어를 할 수 있는 복합 유도법칙을 제안한다. 제안된 유도법칙은 두 가지 형태의 유도명령으로 구성되어 있다. 첫 번째 유도명령은 초기 유도단계에서 탐색기의 지향각(look angle)을 일정하게 유지키기 위한 것이고, 두 번째는 비례항법 유도명령으로서 특정 시선각 조건을 만족시킨 후 적용하여 원하는 충돌각으로 표적을 타격시키게 된다. 제안된 유도법칙은 유도탄의 탐색기 field-of-view(FOV)와 가속도 제한을 동시에 고려하고, 유도명령을 생성시키기 위해 표적 거리정보와 잔여비행시간(time-to-go) 정보가 필요하지 않기 때문에 수동 호밍 유도탄에 직접 적용할 수 있다. 다양한 비선형 시뮬레이션 결과를 통해서 제안된 유도법칙의 특성 및 성능 분석을 수행한다.
