The embodiment of the invention provides a rotary radar time synchronization method, a rotary radar and an agricultural unmanned aerial vehicle. The rotary radar is applied to the agricultural unmanned aerial vehicle and comprises a stator and a rotor, and the rotor rotates relative to the stator. When the photoelectric encoder rotates to a zero position identification gap of the code disc, the photoelectric encoder sends a first electric pulse signal to the signal processor; the signal processor sends a second electric pulse signal to the infrared transmitting tube; the signal processor sends a third electric pulse signal to the rotor micro-control unit; the rotor micro-control unit receives the third electric pulse signal and records the current time as the first moment; the infrared transmitting tube transmits a first infrared pulse signal to the infrared receiving tube; the infrared receiving tube sends a fourth electric pulse signal to the stator micro-control unit; and the stator micro-control unit receives the fourth electric pulse signal and records the current time as the second moment. The time synchronization method provided by the invention has the effects of low time delay and high precision, and the time synchronization efficiency can be improved.
