Angular glint of aircraft formation and its applications

The angular glint of aircraft formation was studied for avoiding it to be intercepted. The angular glint of the aircraft formation was modeled as an evenly distributed N-point scattering center, and the linear error of the angular glint and its distribution characteristics were calculated with the phase gradient method. A mathematical model of the apposition between four aircrafts in different formation modes and a typical surface-to-air missile was established. A simulation was performed by the model. The simulated result shows that it is effective to avoid intercepting with reasonable aircraft formation mode.
