The application discloses a large-interval wide-angle scanning phased array antenna design method and system, and belongs to the technical field of array antenna design. The application adopts parameterized setting of block number to improve the degree of freedom of optimization. Since each block condition may exist a better solution, the block type of the region is substituted into the optimization variable, so that the final optimization result can be prevented from falling into a local optimum, and the optimal solution can be more likely obtained. The dense arrangement form of the divided region can effectively control the interval of adjacent array elements, avoid the overlapping of adjacent array elements, and improve the optimization efficiency. In addition, the regular layout is beneficial to the back-end network design, and reduces the complexity of the feed network. The dense arrangement and array element selection combination can effectively enlarge the interval, and can make the interval not appear grating lobe, thereby reducing the number of channels and reducing the cost. The array element position micro-adjustment provides more possibilities for large-angle scanning optimization, improves the optimization efficiency, and breaks the periodic arrangement form.

This invention discloses a three-degree-of-freedom autocollimation angle measurement device and method based on a crosshair reticle, comprising a probe system, a target mirror system, and a calculation system. The probe system emits a collimated beam containing crosshair image information into the target mirror system. The target mirror system separates the collimated beam containing crosshair image information into two reflected beams parallel to the optical axis, each reflecting beam containing crosshair image information. The probe system also receives the two reflected beams parallel to the optical axis and images the crosshair images corresponding to the two reflected beams. The calculation system calculates the pitch and yaw angles of the target based on the initial and current coordinates of the crosshair image corresponding to one reflected beam parallel to the optical axis, and calculates the roll angle of the target based on the initial and current tilt angles of the crosshair image corresponding to the other reflected beam parallel to the optical axis. This invention enables rapid and high-precision three-degree-of-freedom angle measurement of distant targets.
