A stealthy path planning method for aircraft by constant azimuth

According to the characteristic of Radar Cross Section (RCS) of the aircraft and the Schematic graph of the radar range, Flight with certain constant azimuth can make the generic aircraft which does not have the ability of stealth eluding radars in battlefield. The form of spatial curve that the flying aircraft follows with constant azimuth is first proved, then the algorithm for getting path points on the curve for stealthy flight is proposed, the corresponding flight control rate is solved using variable structure control basing on the simplified equations of motion for generic aircraft. Simulations show that the non-stealthy aircrafts can achieve the purpose of eluding radars by flight with constant azimuth under certain conditions.
