A newly developed digital image injected simulator based on PCI bus is introduced. The system acquires simulation data from the computer using the large capacity of SDRAM as a buffer, the FPGA as the interface and the controller of the state machine. It can provide the simulation data of detector output signal to real-time signal processing system such as the IR warning system or the IR image tracking system. The simulation data coming from the infrared images captured in field test is genuine, real-time, continuous and of high speed, providing a reliable data source for the real-time signal processing system. The software solutions and hardware architecture are given.
