Simulation verification and evaluation of radar BIT system based on multi-signal model

By utilizing the multi-signal model, the simulation-based BIT testability verification and evaluation has lower cost and requires less time than traditional methods, which has lower risk accordingly. The intelligent diagnosis system based on this method integrates the system modeling, testability analysis, diagnosis and presentation, which not only helps to testify the BIT quantitatively, but also helps to improve BIT maturity. Finally the system is applied to a radar assembly for BIT testability verification and evaluation.
