【摘要】：軌跡沖突探測是航空安全的重要保障。傳統(tǒng)的沖突探測方法將目標(biāo)航空器視為點源目標(biāo),忽略其外形輪廓。隨著提高空域利用率需求的增長和量測設(shè)備精度的提高,需要考慮目標(biāo)外形輪廓對沖突探測結(jié)果的影響,否則容易造成漏報和誤判。將擴展目標(biāo)引入沖突探測中,提出了擴展目標(biāo)的沖突探測概率型方法,通過對積分區(qū)域的幾何近似,得到了形式簡潔的沖突概率解析解。與Monte Carlo方法進(jìn)行了比較,仿真結(jié)果表明:在軌跡沖突探測中將大型目標(biāo)視為擴展目標(biāo)是非常有必要的;提出的沖突探測方法是有效的,能夠很好地反映沖突概率的大小和變化趨勢。
[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.
