Abstract: A front-end signal generator for hardware-in-the-loop simulators of a simulated missile is disclosed. The front-end signal generator is driven by the Digital Scene And Reticle Simulation-Hardware In The Loop (DSARS-HITL) simulator. The simulator utilizes a computer to calculate irradiance on an Electro-Optical/Infrared (EO/IR) detector. The generator converts irradiance values into voltages that are injected into the missile's electronics during simulation. The conversion is done with low latency and a high dynamic range sufficient for hardware-in-the-loop simulation. The generator is capable of emulating laser pulse inputs that would be present during laser-based jammer countermeasures. Computer control of the generator occurs via front-panel-data-port (FPDP).
