The hardware-in-the-loop simulation plays a very important role in the research and design process of missile weapons. The architecture of the hardware-in-the-loop simulation system for RF/IR compound guidance was introduced. The model of the passive-wave radar signal based on phase interferometry and the realizing schemes were researched. The hardware-in-the-loop simulation system,which simulated passive-wave radar by signal injection method, was proposed. Experiment results show that the algorithm design of RF/ IR compound Guidance can be tested with the effective support of this system.
