Embodiment Construction

[0024] based on the following Figure 1 to Figure 5 , specifically describe the preferred embodiment of the present invention.

[0025] The present invention provides a method for designing a space-borne phased array signal processing architecture based on an embedded system framework. The method includes the following steps:

[0026] Step 1. Functionally divide the signal processing hardware architecture into a data processing module and a control communication module.

[0027] The control communication module mainly completes the functions of working state control, sending and receiving timing control, and communication with the host computer and other processors; while the data processing module completes the radar data processing functions such as pulse pressure and detection.

[0028] The control communication module makes full use of the UML modular language that comes with the Rhapsody embedded system to design the task state diagram required by the radar processor to ...

Abstract

A design method of space-borne phased array signal processing architecture based on embedded system framework, which divides the hardware architecture of signal processing into functional division, and divides it into data processing module and control communication module, and uses the unified modeling language UML to establish a state control processor The state control process of Rhapsody makes full use of the state jump advantage of Rhapsody's interrupt-driven framework, decomposes the functions of the spaceborne phased array radar processor, and separates the state jump from data processing, making full use of the object-oriented thinking, Realize the pipeline form of data processing, improve the speed of data processing, and improve the maintainability, scalability and portability of the code at the same time.

Description

technical field [0001] The invention relates to a design method of a spaceborne phased array signal processing architecture based on an embedded system framework, in particular to a design method of a spaceborne phased array signal processing architecture based on a Rhapsody embedded system framework. Background technique [0002] With the increasing demand of spaceborne phased array radar signal processing system, the function and complexity of the system continue to increase, and the software quality has become a key factor affecting product performance. It will become more and more difficult to meet the needs of customers for software by continuing to develop non-reusable software by hand, small-scale closed, and the automation of software development will become the trend of software development in the future. [0003] At present, the research on the architecture of the spaceborne phased array radar processor is extensive and in-depth at home and abroad. The traditional ...
