Problems solved by technology
[0004] However, on the one hand, the load platform is constantly enriched, extending from the ground to airborne, ship-borne, missile-borne and space-borne platforms, and the platform has strict requirements on the weight, size and power consumption of the load; on the other hand, As the radar application frequency band continues to increase, the unit spacing of the antenna array decreases accordingly, making the available effective space size of the entire phased array radar array smaller and smaller.

The invention discloses a highly-integrated comprehensive feed network and belongs to the technical field of phased array radar. The highly-integrated comprehensive feed network includes a multifunctional substrate, a plurality of TR modules, a comprehensive feed network cavity and a cover plate. The plurality of TR modules are all disposed at the outer lower end of the comprehensive feed networkcavity. The cover plate is disposed at the outer upper end of the comprehensive feed network cavity. The multifunctional substrate is disposed in a closed cavity formed by the comprehensive feed network cavity and the cover plate. The multifunctional substrate is connected to the plurality of TR modules simultaneously. The highly-integrated comprehensive feed network integrates various networks inside an antenna array surface to realize an integrated design, form an integrated network, improve the degree of integration, and save a large amount of array space. Various functional units are in blinded connection to form a cableless array surface to the utmost extent, thereby reducing the volume and weight of the antenna array surface, and satisfying the requirements of various load platformsfor high degree of integration and lightweight of radar.
Description
technical field [0001] The invention relates to the technical field of phased array radar, in particular to a highly integrated comprehensive feed network. Background technique [0002] Phased array radar is the main trend of modern radar development. With the advancement of technology, whether it is active phased array radar or passive phased array radar, more and more functions are integrated, and the amount and complexity of its equipment are also increasing. Antenna array is one of the core equipment of phased array radar, and its design affects many aspects such as the maneuverability, reliability and maintainability of radar. [0003] Generally, the RF network, control network, and power network inside the antenna array are designed independently. Since each network has no interaction in telecommunications, this design brings some advantages: each professional designer independently designs, and the integration is relatively simple. [0004] However, on the one hand,...
