Low-altitude surveillance radar is mainly used to detect ground, sea and low-altitude targets. It has excellent anti-interference ability, ground/sea clutter suppression ability, and can actively detect and track targets.
The system are using a combination of day light TV and thermal infrared image sensor, steady continuous monitoring and tracking targeted drones.
The long-distance detection and defense integrated equipment ZD02 is a product developed for large areas. The detection distance is up to 10km. The equipment is modularized in management and easy to operate. It can be quickly assembled and deployed according to the actual situation. It can work a...
Navigation Tricking System launch fictitious satellite navigation signal, block the real navigation signal in the air, falsify the navigation system of drones, change the auto location of drones, induce the drone to make a false response and get away from
By jamming the communication channels, the drone is effectively disabled and forced back to its home base or grounded at its current location.
