Stealth-Maneuver Generation for Non-Stealth Aircraft: A Control Barrier Function Approach
Aiming to address the vulnerability of non-stealth aircraft to radar detection due to inherent design limitations, this paper proposes a method to generate maneuvers that reduce an aircraft’s radar cross-section (RCS) value below a specified threshold.

| description | Aiming to address the vulnerability of non-stealth aircraft to radar detection due to inherent design limitations, this paper proposes a method to generate maneuvers that reduce an aircraft’s radar cross-section (RCS) value below a specified threshold. The proposed method employs control barrier functions and leverages the relationship between control inputs and the RCS. Due to confidentiality concerns, the required RCS database for the F-16 aircraft was generated through analyses performed using the created geometry. The results are compared with a virtual path that excludes RCS constraints and does not alter the aircraft’s attitude. Simulations reveal that <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mn>89.6</mn><mo>%</mo></mrow></semantics></math></inline-formula> of the cases using the proposed method achieve a mean RCS value below the threshold, compared to only <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mn>1.26</mn><mo>%</mo></mrow></semantics></math></inline-formula> for the virtual path.
