Problems solved by technology

[0003] On the one hand, the cost of TR components is high, and the number of two-dimensional phased array channels has increased significantly. Each channel corresponds to one TR component. Too many TR components lead to high cost of two-dimensional phased arrays; on the other hand, traditional TR components Integrated with separate devices, the size is relatively large, which significantly increases the volume and weight of the two-dimensional phased array

Abstract

The invention belongs to the technical field of phased array radars, and relates to an X-band high-integration-level two-dimensional phased array radar radio frequency front end. The X-band high-integration-level two-dimensional phased array radar radio frequency front end comprises an antenna housing, active phased array subarrays adopting a silicon-based TR chip, a heat dissipation shell, a power division and synthesis network, a wave control power supply board, a sum-difference network, a frequency synthesizer receiver and a data acquisition board, the heat dissipation shell serves as a main body support, the multiple active phased array subarrays are installed on the heat dissipation shell, heat generated by the active phased array subarrays is conducted to the heat dissipation shell, and the heat is conducted to the two sides of the heat dissipation shell through heat pipes on the back of the heat dissipation shell. The sum-difference network and the wave control power panel are correspondingly arranged on the same plane, and the wave control power panel and the sum-difference network are installed on the back face of the heat dissipation shell and share the back area. The X-band high-integration-level two-dimensional phased array radar radio frequency front end has the characteristics of low cost, high integration level, modularization, strong heat dissipation capability and high reliability, and has rapid maintenance capability.

Description

technical field [0001] The invention belongs to the technical field of phased array radar, and relates to a radio frequency front end of an X-band highly integrated two-dimensional phased array radar. Background technique [0002] Because of its beam agility, phased array antennas can quickly track and search multiple targets, and are widely used in the radar field. At present, due to the constraints of cost factors and TR size, the application of two-dimensional phased arrays is much less than that of one-dimensional phased arrays. [0003] On the one hand, the cost of TR components is high, and the number of two-dimensional phased array channels has increased significantly. Each channel corresponds to one TR component. Too many TR components lead to high cost of two-dimensional phased arrays; on the other hand, traditional TR components The use of separate device integration and large size makes the volume and weight of the two-dimensional phased array significantly incre...
