【摘要】:轨迹冲突探测是航空安全的重要保障。传统的冲突探测方法将目标航空器视为点源目标,忽略其外形轮廓。随着提高空域利用率需求的增长和量测设备精度的提高,需要考虑目标外形轮廓对冲突探测结果的影响,否则容易造成漏报和误判。将扩展目标引入冲突探测中,提出了扩展目标的冲突探测概率型方法,通过对积分区域的几何近似,得到了形式简洁的冲突概率解析解。与Monte Carlo方法进行了比较,仿真结果表明:在轨迹冲突探测中将大型目标视为扩展目标是非常有必要的;提出的冲突探测方法是有效的,能够很好地反映冲突概率的大小和变化趋势。
[Abstract]:The path conflict detection is an important guarantee for aviation security. The traditional conflict detection method regards the target aircraft as the point source and neglects its contour. With the increase of the increase in the utilization rate of the airspace and the improvement of the precision of the measuring equipment, the influence of the outline of the target on the result of the conflict detection needs to be considered, otherwise it is easy to cause misrepresentation and error. The extended target is introduced into the conflict detection, and an extended target collision detection probability method is proposed. Through the geometric approximation of the integral region, a concise analytical solution of the conflict probability is obtained. Compared with the Monte Carlo method, the simulation results show that the large target is regarded as an extended target in the trajectory impulse detection. The proposed conflict detection method is effective and can well reflect the magnitude and trend of the conflict probability.
