Abstract

The invention discloses a method for rapidly determining the tolerance of a hexagonal active phased-array antenna structure based on electromechanical coupling. By the adoption of the method, the problem that when a hexagonal active phased-array antenna structure scheme is designed, the tolerance with a distribution structure is difficult to determine rapidly is solved. The method comprises the steps that the structural parameters and the electromagnetic working parameters of a hexagonal active phased-array antenna are determined; based on an electromechanical coupling model, the electrical performance of the antenna with position installation errors existing in the X-axis direction and the Y-axis direction of an array element respectively and a height error existing in the Z-axis direction is calculated; the deterioration amount, existing when the errors exist, of the electrical performance of the antenna relative to the electrical performance required by the design is analyzed; according to design objectives, the position installation precision of the array element and the array surface flatness are determined, and therefore the tolerance of the hexagonal active phased-array antenna structure is rapidly determined. The method is suitable for rapidly determining the tolerance of the hexagonal active phased-array antenna structures with different frequency bands; by the adoption of the method, deciding and distribution of the position installation precision and the array surface flatness of the hexagonal active phased-array antenna can be guided, and the design scheme of the antenna structures can be evaluated.

Description

technical field [0001] The invention belongs to the technical field of radar antennas, and in particular relates to a method for quickly determining the structural tolerance of a hexagonal active phased array antenna based on electromechanical coupling, which can be used to guide the rapid determination and operation of the structural tolerance of a hexagonal active phased array antenna. Evaluation of structural schemes. Background technique [0002] Active phased array antennas have been widely used in various radar systems due to their incomparable advantages such as high reliability, multiple functions, and good stealth performance. The shape of the source phased array antenna is also different. For example, shipboard radar systems generally use hexagonal active phased array antennas. With the development of military technology in the world, the requirements for the tactics and technical indicators of the phased array radar system are getting higher and higher. Among the...
