Abstract: In this paper, the architecture of radar feature display software is analyzed, extracting three core elements, namely communication management, data management, and display management. Firstly, a communication-data-display (CDD) model that deouples key modules is proposed with the consideration of the current characteristics and requirements of radar feature display, and on the basis of this model, an integrated framework is employed to design the architecture of radar feature display software. Then, the innovative technologies adopted by the three key modules of the CDD model are elaborated separately; in particular, the communication management module adopts network-configurable and multi-threaded subscription distribution mechanism, the data management module employs multi-dimensional hierarchical dynamic memory storage technology and hash data management rules, and the display management module utilizes custom layout and optimized display technology. Finally, the model′s advantages in engineering applications and its implementation effectiveness in practice are verified by comparing the software architecture of the CDD model presented in the paper with that of traditional software design methods.
