Problems solved by technology

[0009] The dynamic update method of CN102404147A does not consider the dependence between software and software, and there are mutual dependencies between software, this update method is not applicable
For the 24-hour uninterrupted environmental detection of the radar system, the update is not autonomous, and the timing of the upgrade needs to be determined according to the operation of the equipment, and the upgrade cycle is long and not real-time

Embodiment Construction

[0025] The embodiments of the present invention are described in detail below.

[0026] The software radar system structure of the present invention is carried out under the C++ language environment, so that the radar components can realize real-time dynamic updating. Such as figure 1 As shown, the software radar system includes: a radar component management center, a radar event manager, a component loader, a radar component service caller, and a radar component database.

[0027] The radar event manager is used to display radar component information on the client side, send management instructions to the radar component management center, and display changes in the radar component in the radar event manager.

[0028] The component loader is used to read the metadata information of the newly-added radar components that have been packaged, and builds a separate radar component loader for each newly-added radar component; the package format of the radar component is a dynamic ...

Abstract

The invention provides a software radar real-time dynamic updating system. The software radar real-time dynamic updating system comprises a radar component management center, a radar event manager, acomponent loader, a radar component service caller and a radar component database. According to the method for analyzing the dependency relationship of the radar components in the radar system, the safety and the stability of the software radar system are improved. The invention further provides a decoupling method between the radar assemblies, the radar assemblies operate independently as services after registration is completed, coupling generated by direct communication between the assemblies is avoided, decoupling between the radar assemblies is achieved, and the radar assemblies do not influence each other any more. According to the system, radar component updating is achieved through C + +, and compared with java type loading, the real-time performance is better; updating can be operated under different platforms supporting a dynamic link library or a shared library, and the advantage of uninterrupted updating is achieved; when the functions of the registered radar assemblies arecalled, the registered radar assemblies operate independently in a service mode, and coupling between the radar assemblies is reduced.

Description

technical field [0001] The invention relates to software radar technology, in particular to a technology for realizing real-time dynamic updating of software radar under the environment of C++. Background technique [0002] Software-based radar is an open architecture, a new generation of radar technology that defines, expands, and reconstructs radar system functions through software. In the complex and changeable battlefield environment, the software-based radar takes high-speed, short-latency, and high-capacity efficient processing as the constraint boundary to realize the openness of the processing platform, decoupling of software and hardware, reconfigurable hardware, and reconfigurable software. Software-based radar can customize radar functions according to requirements, flexibly respond to a variety of different radar operational requirements, and cover various application scenarios such as detection, jamming, reconnaissance, and communication. [0003] Software-base...
