Abstract

Abstract:

Because the working process and interface interactions of radar systems are currently mainly described in the text form, the overall verification of the system has become overly reliant on physical objects, leading to issues such as long verification cycles and high design correction costs. In view of the problems existing in the development process, this paper adopted the idea of MBSE to carry out radar operation scenario-oriented demand analysis. According to the maturity and complexity of the radar system function, it elaborated on the functional analysis methods suitable for different radars, and emphasized the radar system and subsystem architecture design and three-level simulation verification method. By advancing part of the verification link in the system debugging stage to the initial stage of system design, the paper solved the pain point problem of over-dependence on physical objects, which held significant implications for the application of a new development mode for radar systems.

Key words: radar scenario, requirement analysis, functional analysis, architecture design, simulation verification
