“…α is the aircraft manoeuvring frequency. For specific forms of F k , U k , and q cs refer to [2, 4–6]. σ a 2 is the variance of manoeuvring acceleration complying with the mended Rayleigh distribution: However, due to the inaccessibility of ā k+ 1 , the following approximation is implied in the CS model [29]: where Z k is the set of measurements in time 0– k .…”
