Abstract

The objective of the invention is to solve the problem of five-to-eight radar communication equipment in the prior art. In order to overcome the defects of long-term factory customization, high maintenance cost, difficulty in upgrading and the like in the prior art, the invention provides software radar universal communication middleware which is designed through a hierarchical architecture and mainly comprises: 1) a publishing / subscribing interface layer for providing a unified API interface for a service application software layer; 2) a real-time information exchange layer which completes the analysis and conversion of a message; and 3) a transmission control layer which provides a standard and simple communication link interface for the real-time information exchange layer. Unified andopen interfaces are defined among the layers, the layers are independent from one another, the design, upgrading and updating of each layer cannot influence the operation of other layers, the development efficiency is greatly improved, and the maintenance cost is reduced. Different communication protocols are supported, and communication among different components in the radar nodes, distributed system communication of different computing nodes, communication among boards, cores, processes, threads and the like are supported.

Description

technical field [0001] The patent of the present invention relates to the field of software-based radar, specifically a distributed general-purpose communication technology of software-based radar. Background technique [0002] With the increasingly complex electromagnetic environment in the current battlefield, the increasing number of electronic warfare equipment, the rapid development of wireless communication technology, and the variety of communication product styles, the traditional hardware-based communication methods can no longer meet the needs of the current and future markets. Therefore, research A model that can achieve unified data distribution on different devices is of great significance. The software-based radar communication middleware is designed to solve the diversity of current communication methods and promote the development of high-performance processing platforms. [0003] Avionics system technology is a comprehensive distributed communication applic...
