Description

Technical Field

[0001] The invention relates to the field of radar information technology, and in particular to a reconfigurable design method for a scene-oriented measurement radar back-end information processing system. Background Art

[0002] Measurement radar is a radar that acquires target location information and electromagnetic scattering characteristics by detecting, capturing and continuously tracking targets. It has diverse functions and a wide range of uses. It is an important means of radio external measurement in aerospace measurement and control systems. With the rapid development of my country's aerospace industry, space launch missions are becoming more and more dense, which places increasingly higher demands on the control and use performance, maintenance and upgrade convenience, and the ability to adapt to diversified tasks of measurement radars. Traditional measurement radar is designed to achieve special functions. The system function and device architecture are tightly coupled. In the back-end information processing, proprietary hardware and software architecture is used according to the functional performance requirements. Hardware configuration and software development are carried out independently. The design of application software is mainly based on specific scenarios and hardware architectures. There is a lack of unified design requirements and specifications for software architecture in advance, which leads to the following limitations of traditional measurement radar: 1) The signal processing, data processing and other subsystems of the radar back-end are tightly coupled and interconnected based on special interfaces, and there is no interface standard for functional division, calculation, communication and other aspects, making it difficult to replace and upgrade hardware and software; 2) Radar is a complex embedded system with tight coupling of hardware and software. System upgrades and renovations require the redevelopment of the entire radar system, making it difficult to quickly apply new functions and new algorithms and port them across platforms; 3) For specific scenarios, application software is deployed in advance on a fixed hardware platform to run, and system resources and data are statically allocated. The static deployment method of application functions and hardware binding is difficult to meet different application requirements, making system upgrades and reconstructions difficult.
