本发明涉及相控阵技术领域，更具体涉及一种多波束相控阵集成系统及方法。The invention relates to the technical field of phased arrays, and more particularly to a multi-beam phased array integration system and method.
背景技术Background technique
多波束相控阵天线是目前卫星载荷中最重要的一种天线形式，具有灵活的波束控制能力，波束间独立控制，可同时服务多个用户，也可在不同用户终端之间快速跳变。从国外通信卫星发展来看，最新发射的通信卫星系统多数搭载了一幅或多幅相控阵天线，提高波束的调度灵活能力，与反射面天线形成能力相互补充。随着卫星工作频率逐渐增高，毫米波频段由于其高带宽、小尺寸、轻重量和较好的抗干扰特点，在通信卫星中广泛使用。Multi-beam phased array antenna is the most important antenna form in satellite payloads at present. It has flexible beam steering capability, independent control between beams, can serve multiple users at the same time, and can also quickly jump between different user terminals. From the perspective of the development of foreign communication satellites, most of the newly launched communication satellite systems are equipped with one or more phased array antennas to improve the flexibility of beam scheduling and complement each other with the ability to form reflector antennas. As the operating frequency of satellites gradually increases, the millimeter-wave frequency band is widely used in communication satellites due to its high bandwidth, small size, light weight and better anti-jamming characteristics.
然而多波束相控阵通道规模大，是波束数量和通道数量两个维度的矩阵，即包含“M波束×N单元”个通道，特别是毫米波相控阵，尺寸小，阵元数量较多，多波束形成时，波束形成网络内包含大量的通道，以400阵元，8波束为例，需要在有限的空间内实现3200个波束通道，若不进行集成，系统的复杂度、设备量、体积和重量将会非常庞大，几乎不可能在星载平台上使用。However, the multi-beam phased array channel scale is large, and it is a matrix of two dimensions: the number of beams and the number of channels, that is, it contains "M beam × N units" channels, especially the millimeter wave phased array, which is small in size and has a large number of array elements. , In the case of multi-beam forming, the beam forming network contains a large number of channels. Taking 400 array elements and 8 beams as an example, 3200 beam channels need to be realized in a limited space. The volume and weight will be so huge that it is almost impossible to use it on a spaceborne platform.
毫米波两维有源多波束相控阵面临的问题就是在有限的空间内实现高复杂度波束形成网络的系统集成，一个好的集成方案对系统可实现性、装配可操作性、质量可靠性、复杂度以及系统散热等均会带来质的飞跃，因此一个合理的集成化方案是毫米波两维多波束相控阵的核心。The problem faced by the millimeter-wave two-dimensional active multi-beam phased array is to realize the system integration of the high-complexity beamforming network in a limited space. , complexity and system heat dissipation will bring about a qualitative leap, so a reasonable integrated solution is the core of the millimeter-wave two-dimensional multi-beam phased array.
既然波束形成网络是波束数量和通道数量两个维度的矩阵，可以在通道维度和波束维度集成，将波束形成矩阵划分成若干个“m波束×n单元”的子矩阵进行集成。Since the beamforming network is a matrix of two dimensions, the number of beams and the number of channels, it can be integrated in the channel dimension and the beam dimension, and the beamforming matrix can be divided into several sub-matrices of "m beam × n units" for integration.
随着子矩阵规模的变大，系统设备量、体积、重量、复杂度将会增加。但是并不是集成规模越大越好，过大规模的集成度将会带来以下缺点：子阵的体积过大，影响系统安装空间划分的灵活性和空间利用率；随着规模的增加，子阵内部的功分合成网络越复杂，子阵内部的体积利用下降；规模越大集成难度越大，给设计加工带来困难。As the scale of the sub-matrix becomes larger, the amount, volume, weight and complexity of the system equipment will increase. However, it is not that the larger the integration scale is, the better. Excessive large-scale integration will bring the following disadvantages: the volume of the sub-array is too large, which affects the flexibility and space utilization of the system installation space; as the scale increases, the sub-array will The more complex the internal power division synthesis network is, the smaller the volume utilization inside the sub-array is; the larger the scale is, the more difficult it is to integrate, which brings difficulties to the design and processing.
