Summary:The invention provides a multi-physics field coupled phased array guidance microsystem collaborative optimization method. The method comprises the following steps: respectively establishing a structural finite element model, a thermal analysis model and a force analysis model of a phased array guidance microsystem; establishing a corresponding structure temperature difference load; obtaining a structure displacement field; determining a space phase error of the radiation unit; obtaining a sum-difference directional diagram of an antenna unit of the phased array guidance microsystem; calculating electrical performance parameters of the phased-array antenna; obtaining the pointing precision of the phased array guidance system; judging the pointing precision, if the requirements are met, completing collaborative optimization of the system, and otherwise, modifying design parameters of the structural finite element model, the thermal analysis model and the force analysis model until the requirements are met.
