为了应对战场环境的瞬息万变,以及适应任务变更的需要,在线规划对于飞行器来说非常有必要。然而,由于飞行器不可能在空中长时间地停留,因此在线规划对规划速度的要求是非常苛刻的。基于航迹片段的航迹规划方法是一种能够有效地提高在线航迹规划速度的方法,其中航迹重组是这种方法的主要组成部分。本文根据航迹重组的自身特性,设计一种基于航迹片段的多核DSP并行航迹规划方法。实验结果表明,所设计的方法并没有影响航迹代价,而且在多核DSP上能够获得较高的加速比,能够有效地提高航迹规划速度。
In order to cope with the ever-changing battlefield environment, as well as to meet the needs of mission changes, online planning is very necessary for the aircraft. However, as the aircraft can not stay in the air for a long time, the requirements of online planning for planning speed are very harsh. The track planning method based on track segments is a method that can effectively improve the speed of online track planning. Track reorganization is the main part of this method. According to the characteristics of track recombination, this paper designs a multi-core DSP parallel track planning method based on track segments. The experimental results show that the proposed method does not affect the track cost, and can obtain a higher speedup ratio on the multi-core DSP, which can effectively improve the track planning speed.
