The invention discloses a micro-nano satellite formation multi-target attitude control method and system based on an array antenna. The method comprises the following steps: firstly, initializing a micro-nano satellite formation model; wherein the micro-nano satellite formation comprises a master spacecraft, a service spacecraft and any slave spacecraft which form a master-slave structure; then calculating a bidirectional LOS vector by using an MIMO communication technology and a CDMA technology; and finally, according to the bidirectional LOS vector and the angular velocity of the spacecraft, calculating control input, so that the control input reaches an expected relative attitude, and completing multi-target attitude control of the micro-nano satellite formation. The method reduces the dependence on a high-precision sensor, reduces the cost, improves the reliability and flexibility of the system, can achieve the precise attitude control of each satellite in the micro-nano satellite formation, and can be widely used in the technical field of micro-nano satellite formation attitude control.
