[Abstract]:As an important part of radar system, radar target display and control terminal must be able to accurately control radar system, be responsible for displaying radar target information, state information, GPS positioning and other information, and is a platform for operators to interact with radar system. In this paper, the research of radar display and control terminal based on embedded system is carried out, and the intelligent terminal of radar display control is designed and realized by using advanced embedded technology, which is of great significance to improve the performance of portable short-range battlefield reconnaissance radar. In this paper, the functional requirements of radar display and control terminal are comprehensively analyzed, the main functions and technical performance indexes of embedded radar display and control terminal are put forward, and the overall hardware scheme and software system architecture of radar display and control terminal based on embedded technology are designed. Samsung Exynos4412 processor is selected as the core component of embedded system, on the basis of which the hardware platform is established. Secondly, in order to meet the real-time requirements of the system, embedded Linux is selected as the operating system of the system, and a cross-compiling environment based on the target machine-host mode is built. As an important part of the system design, the display and control terminal software adopts modularization design, including: human-computer interaction interface design based on Qt/Embedded; radar parameter setting module design; radar state display module design; radar target display module design under B display and P display mode; communication module design based on Ethernet and serial port. Finally, the software of the display and control terminal is ported to the hardware platform for system adjustment, which fully verifies the correctness of the design of the embedded display and control terminal system.
