The invention discloses a radio-frequency signal simulation control method, which is based on a radar countermeasure test semi-physical simulation system radio-frequency signal equivalent control principle to ensure that the interference-to-signal ratio of signal control is equivalent and consistent in a test process. Comprising the following steps: determining a control reference signal M: a semi-physical simulation system calculates target echo signal power and interference signal power of each simulation period under the driving of a test battle condition; when the power of the target echo signal is smaller than that of the control reference signal M, the interference signal and the target signal are controlled according to the absolute size of actual calculation; and when the target signal is increased to the control reference signal M, the target power is kept unchanged at the reference power, and the interference signal is normalized according to the reference signal under the condition of ensuring that
