The invention discloses a high-enthalpy flow field radiation heat flow test system and method, when an aircraft flies at a high speed, due to the fact that the stagnation point temperature of the aircraft is extremely high due to strong pneumatic heating, and meanwhile radiation heating is very strong due to the high temperature of a shock wave layer, the radiation phenomenon intensifies surface heating; the cumulative effect caused by long-time radiation heating can challenge a heat protection system. According to the invention, a large-size free piston pulse wind tunnel is utilized, a high-enthalpy flow field radiation heat flow test system and method are established based on a high-spatial-resolution optical radiation and thermal radiation characteristic refined identification technology, and the radiation heat flow proportions of ultraviolet, visible light and infrared wave bands and spectrums with large radiation intensity in total radiation heat flow are obtained. Accurate verification data is provided for theoretical modeling and numerical simulation analysis research, and low-redundancy fine design of a novel aircraft is supported.
