The invention discloses a multi-point array response control directional diagram synthesis method with the maximum gain. The method comprises the steps of determining an expected directional diagram, a preset normalized level value, a preset weight vector and a steering vector of an expected signal; selecting a plurality of to-be-controlled angles to obtain a to-be-controlled angle set; according to the angle set, determining a complex constant set and distribution characteristics of a real part and an imaginary part corresponding to complex constants; determining a target complex constant according to the distribution characteristics; determining a to-be-determined directional diagram according to the target complex constant; judging whether a graph difference value between the to-be-determined directional diagram and the expected directional diagram is smaller than a preset threshold value or not; when the graph difference value is smaller than the preset threshold value, determining the to-be-determined di
