Problems solved by technology

Use multiple frequency bands with overlapping antennas to cover wide-area frequency bands, resulting in complex electromagnetic compatibility issues
The increase of electronic equipment not only consumes a lot of energy, occupies more space, reduces the payload of the platform, but also weakens the maneuverability of the platform, increases the radar target reflection cross-sectional area, and reduces the anti-interference ability and modern weapons in the modern electromagnetic environment. Combat effectiveness of equipment systems

Abstract

The invention proposes a multifunctional and integrated radio frequency integral implementation method based on the apertures. According to the method of the invention, a special L-shaped array is formed by using an ultra-wide-bandwidth wide-angle scanning planar phased array antenna unit to realize antenna aperture sharing, multiplexing and function reconfiguring. Through the arrangement of an attenuation mode for the transmitting and receiving components, the dynamic selection and distribution of the sub-matrixes of reconnaissance, the interference, the detection and communication are realized. The radio frequency integral method realizes the high-degree cooperation of the perception of multi-source information and the various radio frequency functions, which not only guarantees the realization of each single function index, but also makes full use of the data and information of each function module to carry out the integrated processing so that the different functions enhance each other and that the overall performance is raised.

Description
