Predictive control of aircraft control systems for maneuverable target

Synthesis of Algorithm to Change Guidance Law for Air-to-Air Missiles Intercept Separating Targets

“…7, the Doppler signal spectrum reflected the carrier target (1), and in Fig. 8, the Doppler signal spectrum reflected both the carrier target (1) and the separating target (2). The first condition in the algorithm of selecting the target and converting to guidance law is that the number of the group separating targets increases.…”

“…There have been substantial research and development of missile guidance laws [1][2][3][4][5][6][7], each of which has its own optimal criteria according to energy, error, fast acting, and ability to distinguish targets. Currently, there is no guidance law that can optimally meet all the criteria as stated, especially for all target audiences.…”

“…For "air-to-airˮ intercept missiles, guidance laws are based on proportional guidance law PN [7], which has different variants depending on the selected optimization criteria. The advantage of the PN guidance law in [2,4,7] is that the missile's trajectory has a relatively small initial curvature and miss distance, resulting in a high probability of destroying the selected target, while the guidance law APN can intercept maneuvering targets [1,5,6]. However, a drawback of the PN and APN guidance laws is that their approaching trajectory is relatively straight, which is a disadvantage connected with detecting each target in the group at a long distance separately, especially the opponent's countering missiles called the separating target.…”
