1. Features & applications
The DAF2 UAV Visual Guidance System is an advanced visual guidance solution designed for high-speed target tracking and precise strikes. It integrates a colorless Kalman filter terminal guidance law with a low-latency target tracking algorithm to accurately predict target positions. The system uses a proportional navigation algorithm to adjust the UAV's flight vector in real-time based on the angular velocity of the target line-of-sight. With its FPGA hardware-acceleration architecture, it achieves microsecond-level target locking and precise terminal guidance, making it ideal for high-speed target tracking and precise strike scenarios. The system offers three variants: DAF2 A, DAF2 HD, and DAF2 DU, each with different specifications to meet various application requirements.
2. Product Features
