Time-varying Target Characteristic Analysis of Dual Stealth Aircraft Formation

Based on the research background of target formation characteristics of dual stealth aircraft, how to effectively compare and analyze the actual change characteristics of target formation RCS under different formation flying modes in penetration operation is discussed. The model of two-plane horizontal flight path, two-plane hovering track and two-plane formation infiltration maneuvering track are proposed. Based on the model, the attitude sensitivity of dual stealth aircraft formation is analyzed firstly, and then the line-of-sight attitude angle of dual stealth aircraft formation is calculated. Based on the static RCS data of dual stealth aircraft in the whole airspace, the time-varying dynamic RCS sequence is simulated. The simulation results show that the real-time RCS sequence distribution of the two-aircraft formation is more suitable than that of the single-aircraft formation at 150 meters interval when compared with the real-time RCS sequence of the single stealth aircraft under three different track attitudes, and the formation has less influence on the stealth performance.
