Abstract

The invention provides a surface type high-precision adjustment method for a phased array radar under a large-load working condition. The method comprises the following steps: constructing an originalequation of a phased array radar array element surface; calculating the maximum deviation between the actually installed phased array radar array element surface and the original equation thereof; calculating the maximum deviation of the form and position change of the phased array radar array element surface; calculating the position and attitude parameters needing to be adjusted of each phasedarray radar array element, and calculating the actual installation position of each phased array radar array element; unloading the weight of the phased array radar array element; adjusting the position and attitude of each phased array radar array element; calculating an adjustment parameter of each phased array radar array element; and adjusting each phased array radar array element. According to the method, the actual installation parameters of each phased array radar array element are measured, adjustment parameters are obtained through calculation, adjustment of the positions and posturesof the array elements in the loaded state is completed through the array element weight unloading mechanism and the array element adjustment mechanism, and high-precision adjustment and control of the whole surface type of the phased array radar under the large-load working condition can be achieved.

Description

technical field [0001] The invention belongs to the technical field of optical precision measurement and testing, and in particular relates to a high-precision adjustment method for a phased array radar surface profile under heavy load conditions. Background technique [0002] Large-scale phased array radar has the characteristics of long range, high data rate, multiple target tracking and high measurement accuracy. It provides spatial position information for long-range and precise strikes to meet the needs of information warfare. With the development of offensive weapons such as intercontinental ballistic missiles, submarine-launched ballistic missiles, multiple-warhead guided re-entry missiles, and various satellites, the demand for large-scale phased array radars has also increased sharply. [0003] The overall installation accuracy of the element plane of phased array radar is the key index for radar to obtain good performance. However, the increase of the caliber of t...
