Study of Time Delay Characteristic of HITL Simulation System for Laser Angle Deception Jamming

The simulation of sequential relationship is an important part in the laser angle deception jamming of half size hardware-in-the-loop (HITL) simulation system. The time delay characteristic of system is studied to set the ahead time of deception jamming accurately. The laser angle deception jamming of HITL simulation system and jamming theory are introduced, and the primary cause of system time delay is analyzed. A system time delay characteristic model is established based on time delay measurement of single device. The proposed model is verified by means of the laser angle deception jamming for HITL experiment under typical working condition. The measured results show that the peak-to-peak value of system delay time is less than 230 ns, which is coincident with simulated results of the model.
