Abstract:As radar technology evolves towards informatization, unmanned operation, and intelligence, the demand for comprehensive and thorough testing grows increasingly urgent. However, traditional testing methods are constrained by cost and time, making it difficult to meet these requirements. This paper first analyzes the background and necessity of digitalized testing, then discusses the key technologies for radar digitalized testing transformation from three aspects: complex environments, performance baseline, and integrated connectivity. These discussions provide references for research directions in the field of testing digitalization transformation.
