Design of Virtual Training System for Radar Maintenance Based on 3D Virtual Reality Technology

The traditional radar maintenance virtual training system is affected by linear filtering, resulting in poor training effect. In order to solve this problem, a radar maintenance virtual training system design based on 3D virtual reality technology is proposed. According to the hardware topology of radar virtual training system, the internal component virtual machine of each extension is designed. The instructor console is set to control the operation of the whole system, and an 8 serial port card is installed on the display console to determine the fault location. The antenna structure is designed by coupling feed technology, which is used to reduce the coupling degree of different elements in high frequency section. The three-phase 380V municipal power is converted into multiple AC220V through the distribution box, and the control of the transceiver cabinet is completed through the control and protection extension, the transmitter extension and the receiver extension. The 3D virtual reality soft shadow technology is used to accelerate the hardware, and the results are stored in the shadow texture, so the virtual training process is designed. According to the experimental results, the radar fault signal accuracy of the system can reach 99%. The virtual training content of fault maintenance can also solve various fault problems, with good training effect, and effectively meet the needs of radar maintenance training.
