Mounting bracket for T/R assembly of hemispherical phased array radar

Abstract

The invention provides a mounting bracket for T / R assembly of hemispherical phased array radar, which aims at providing a mounting bracket which has high reliability and high integration and can be easily mounted and maintained. The invention is realized by the following technical schemes. The upper end is provided with a support turn cover (3) and a support body (2) whose free end is provided with an adapter plate (4).The support turn cover and the support body are fixedly connected to a back arc shape support plate (1) with a two-layer staggering structure. The adapter plate is fixedly connected to the front end of the support body with an independently moveable installation unit. An attached bracket (5) is inserted fixedly into the arc shape support plate (1) through the docking face between the two layers of the staggering support box and from the front side face at two ends from the head to the tail of the lower layer of the support box respectively; a power distributor (7) and two power dividers (6) at two sides of the power distributor (7) serve as attached components that are fixedly arranged on the front plate of the support to assemble a component array (10). Finally, all component arrays are fixed to the inner side of the spherical hemisphere phased array radar.

Description

technical field [0001] The invention relates to a mounting and maintenance bracket mainly used for large hemispherical phased array radar T / R components. Background technique [0002] The planar phased array radar XBR of the United States is an X-band multifunctional broadband phased array radar with an antenna area of ​​123 square meters and a total of 81,000 T / R components; the AN / TPY-2 phased array radar also works in the X-band, and the antenna With an area of ​​9.2 square meters, there are 25,344 T / R modules in total. The surface area of ​​a certain type of phased array antenna in China exceeds 150 square meters, and the number of T / R components exceeds 22,000. For a hemispherical phased array radar with a diameter of more than 10 meters, the surface area exceeds 160 square meters, the number of T / R components will exceed 24,000, and the total number of internal cables exceeds 80,000, with an average length of each cable of 12 meters. If the annual failure rate of 24,...

Problems solved by technology

There are four major difficulties in the traditional installation method: First, if 20,000 metal brackets are installed, 80,000 holes need to be tapped inside the spherical surface of the hemispherical phased array radar. The workload is heavy and the tapping positioning of many holes is not accurate, resulting in The screw installation is skewed or cannot be installed; second, the traditional bracket does not have an adapter plate or an independently movable adapter plate, which requires multiple installation and removal of connecting cables when replacing the module; third, the traditional bracket is not placed on the T / R The accessory support frame at the back end of the module causes the power divider and power distributor to be too far away from the module, increasing a large amount of invalid wiring length, resulting in a large number of cables at the back end of the module like a waterfall, which seriously blocks the module and causes a huge Waste the limited space inside the sphere, and more importantly, greatly increase the cost of using cables

Fourth, because the traditional installation method does not implement the module sub-array modular installation method, all T / R components and their brackets are installed separately on the inside of the sphere of the hemispherical phased array radar, and all installation work must and can only be done on the sphere Internal completion, resulting in difficult installation and low efficiency

Therefore, using the traditional installation method to install T / R components, when the number of installed components reaches tens of thousands or more, the waste of manpower, material resources and time is amazing
