航空瞄准新算法AFA的剖析与改进

Analysis and Improvement on a New Aerial Aiming Algorithm AFA

AFA(Asynchronous Fire Aiming,非同步射击瞄准)算法是一种新的航空瞄准算法,消除了经典航空前置跟踪瞄准算法LCOS(Lead Computing Optical Sight,前置计算光学瞄准)存在瞄准稳环的弊端。分析了LCOS存在瞄准稳环弊端的根本原因,并在此基础上深入剖析了AFA算法消除瞄准稳环的原理与核心技术。同时,指出AFA算法存在的"瞄准环构成超限"缺陷,并针对此缺陷提出了改进方案,进一步完善了AFA算法。

AFA（Asynchronous Fire Aiming） algorithm is a new aerial aiming algorithm, which eliminates the defect of LOAR（leveling off the aiming-ring） in LCOS（Lead Computing Optical Sight,a classic aerial lead tracking aiming algorithm）.This paper analyses the essential causation to LOAR, and studies thoroughly the principle and key technique for eliminating LOAR. Further more, a shortcoming of ＂creation of aiming-ring beyond limit＂ is pointed out in AFA. And then a solution to the shortcoming is proposed, which improves AFA effectively.
