The invention discloses a TACAN range finding method under a silent condition, which comprises a range finding method based on double-station or multi-station direction finding intersection and a fusion processing method based on flight information auxiliary information, the range finding method based on the double-station or multi-station direction finding intersection is based on direction finding information of double tower stations or multi tower stations received by a TACAN, calculating the distance measurement from the airplane to the platform by adopting a geometric cross distance measurement method, and obtaining the three-dimensional coordinate positioning of the airplane in combination with the height information; according to the information fusion processing method based on flight information assistance, three-dimensional coordinate positioning, three-dimensional speed and three-dimensional acceleration of an aircraft serve as state variables, three-dimensional coordinate positioning of the aircraft serves as observed variables, smooth filtering estimation is conducted on the position of the aircraft through a Kalman filtering method, and position information output outwards is obtained. According to the invention, the continuous and reliable distance measurement function of the TACAN under the silent condition is realized.
