Abstract: In order to adapt to the complex battlefield space and improve the armored vehicle's short distance protection ability and battlefield survivability, a vehicle 360° situational awareness system was proposed. The framework of the system was given, and the key technologies such as general design, high throughput of embedded image processing platform, real-time panoramic mosaicing, target recognition and threat estimation were analyzed. Then the solutions were put forward. Results show that this system realizes the high-definition image mosaic in multi-channel. The delay time is better than 190 ms, and the detection distance to the vehicle is up to 1 km. It has the abilities of detection and threat prompting for human and vehicle targets, and can improve the situation awareness of armored vehicles in near range significantly.
