Modeling and Analysis of Errors on Array Hardware-in-the-loop RF Simulation System

Array hardware-in-the-loop simulation system is an ideal environment for weapon direction system carrying out the antijamming trial. It plays an important role in the development of the weapon direction system. The accuracy of the target location is a critical indicator of the array hardware-in-the-loop simulation system. Error factors and the reasons of error are analysed from many aspects, such as basement infrastructure, steel structure, array antenna, microwave link, calibration system and others correlated, which all may arouse the accuracy of the target location. What's more, the corresponding improvement actions are proposed.
