Description
Technical Field
The invention relates to a phased array antenna, in particular to an active phased array antenna with a columnar layered surrounding framework.
Background
The active phased array antenna is a key component of an electronic task system such as radar, communication, electronic warfare and the like, bears the tasks of radiating electromagnetic waves outwards and receiving space electromagnetic waves, and is a necessary path for the electronic task system to acquire external information through the electromagnetic waves. In the design of an active phased array antenna, on one hand, stable and excellent electrical performance needs to be pursued; on the other hand, many engineering realizability problems need to be solved, which mainly include: the device is installed in cooperation with a platform, performance evaluation and test in the early stage, disassembly and maintenance in the later stage, yield, manufacturing cost and the like. In general, the latter problem is mainly solved by the architectural design of the active phased array antenna.
A typical active phased array antenna mainly includes a passive antenna array, a transceiver module, a beam forming network, a wave control board, a cable module, and other functional modules. At present, the common active phased array antenna architecture mainly comprises three types of structures, namely a separated type, a brick type and a tile type (1. Pengxinlong, phased array antenna integration technology, telecommunication technology, 2010,50(10): 112) 117; 2. Tangbaofeu, Dianfeng, consider Yeqing, active phased array radar antenna structure design, the university of Western electronic technology publisher, 2016).
The functional modules in the separated framework are distributed and arranged and are connected with each other through a cable assembly. The structure has simple structure, low cost and convenient disassembly and maintenance, and is commonly applied to a foundation-fixed large-scale electronic task system. However, the structure has low integration level and large occupied space, and is difficult to apply to high-speed motion platforms with limited space, such as missiles, airplanes, satellites and the like.
The tile architecture is a high-density architecture in which individual functional modules and structural members are assembled in a stack, typically in a "sandwich" configuration. The passive antenna array surface is arranged on the top, functional layers such as a receiving and transmitting assembly layer, a heat dissipation layer, a beam forming network layer, a wave control and power supply layer are arranged below the passive antenna array surface from top to bottom respectively, and the layers are interconnected through blind connectors. The tile architecture has high integration, low profile, light weight, and small volume (Haughan, medium, development of a broadband multi-channel tile T/R component, telecommunication technologies 2015, 55 (1): 108-. However, the architecture has the following problems in engineering application due to high integration: firstly, the heat dissipation is difficult, and the use in a high-power electronic task system is not facilitated; secondly, the yield is low, a tile type structure usually integrates a plurality of to more than ten transceiver modules, and if a certain transceiver channel in the middle fails, the whole subarray fails; thirdly, the testing and the maintenance are difficult, all functional layers are connected through blind connectors, and the disassembly is very difficult or even impossible. The latter two problems result in the high cost of manufacturing tile-structured active phased array antennas. (Zhao Qing, a Ka-band tiled TR-module sub-array integration scheme, telecommunication technologies 2012, 52 (7): 1155-.
The brick architecture is relative to the tile architecture. Each functional module in the brick block type framework is packaged by adopting a box, and a plurality of to more than ten signal channels are integrated in each box. The functional modules are connected with each other mainly through blind-mate connectors, and cable assemblies may be used in some places. The high integration level is kept, and meanwhile, the functional modules are relatively independent, so that the active phased array antenna with the structure has strong testability, maintainability and expansibility. The method is widely applied to missile-borne, airborne and satellite-borne platforms. The framework to which this patent relates can be categorized as a brick-type framework.
Currently, the Active Phased Array Antenna with brick-type structure is applied in the aspects of onboard fire control radar, onboard communication payload, and the like, typical examples include fire control radar AN/APG-77 and AN/APG-81 (1. institute of airborne industrial radar and electronic equipment, airborne radar handbook, 4 th edition, 2013, 176-186; 2. money, etc.; structural design of onboard Active Phased Array radar Antenna front, modern radar, 9.2012, 66-68), fire control radar AMSAR (Albarel et al, advanced Antenna and predicted Performance, IEEE Systemd Array Systems and Tech, 1996) developed by WIND three countries for the "gust" fighter combined with the fighter, and Active Phased Array APPA (Nakato Antenna adaptive system and technology, 1996) developed by WINto communication satellite DS, european antenna and transmission conference, 2006).
The common feature of the above architectures is that each functional module of the active phased array antenna is in a cascade blind matching relationship, i.e., the front end is an antenna array surface, and the rear is sequentially cascaded with the functional modules of a transceiver module, a beam forming network, a wave control and power supply, etc. In the application occasions of low frequency bands (lower than X wave bands, such as AN/APG-77 and AN/APG-81 in the United states) or the application occasions of a small number of simultaneously formed wave beams (less than 3, such as 2 of APAA in Japan) and the like, the transverse sizes of the modules of the transceiving component, the wave beam forming network and the like of the structure are matched with the distance between the antenna units, so that the cross section of the whole active phased array antenna is equal to or slightly larger than the aperture of AN antenna array surface, the whole active phased array antenna is cylindrical, and the active phased array antenna can be conveniently installed on platforms such as airplanes, satellites and the. However, in applications with limited technology level (such as the aforementioned european AMSAR), or operating in high frequency band (above 30GHz), or with a large number of beams formed simultaneously (greater than 3), the cross-sectional area of the transceiver module and the beam forming network will be difficult to design to match the antenna element spacing, often the former being larger than the latter. This results in the active phased array antenna being generally pyramidal (as in the aforementioned european AMSAR), which imposes special requirements on the mounting platform. In some platforms, it may even be disabled.
In summary, in the above-described existing architecture, the functional modules of the separated architecture are distributed and connected to each other through cables, so that the integration level is too low; each functional module of the tile type framework is distributed on different layers, and the layers are interconnected through blind connectors, so that the tile type framework cannot tolerate high power, has low yield and is difficult to maintain; each functional module of the traditional brick type framework is independently packaged, and the active phased array antenna is in a non-cylindrical shape through blind matching connector cascade connection on the occasions with limited process level and high frequency band or more simultaneously formed wave beams, so that special installation requirements are provided for a platform, and even the platform does not permit the active phased array antenna.
