The invention relates to the route smoothing and tracking control technology field and discloses a cruise missile air route second-order smoothing method. The cruise missile air route second-order smoothing method comprises steps that symmetrical polar polynomial curve route smoothing, missile motion equation feedback linearization and optimal controller designing are carried out; a cruise missile route is decomposed to be smoothing transitions of multiple adjacent route segments, a symmetrical polar polynomial curve is introduced to a route smoothing process, and a second-order smoothing route satisfying cruise missile performance constraints is generated; a feedback linearization method is employed to establish a cruise missile linearization model; a route tracking problem is converted into a tracking control problem of a virtual missile, and a locus tracking controller is further set. The method is advantaged in that a symmetrical polar polynomial is employed as a route smoothing curve, so route second-ord
