Anti Drone system (CUAS)
Zen ADS is a Multi-Layer Multi Sensor Architecture aimed at providing comprehensive security against all classes of unmanned aerial system attacks.
The different modules of Zen ADS are :
RF BASED DRONE DETECTOR (RFDD)
RFDD detects the drone using Radio Frequency (RF) communication between the drone and Ground Control Center (GCC). This system is on continuous search mode on a wide band of frequencies that are typically used by the drone and its GCC. Whenever a frequency of interest is identified, the system locks and monitors the signal. Based on the identified signal, the system estimates the direction of the drone and its GCC. An array of receiving antennas is used for estimation of signal direction.
RADAR DETECTION
Detection of autonomous drones (flying without a link between drone and operator) using RFDD is not possible. RADAR is the best choice to detect such threats. A RADAR detects the drones according to the maximum range chosen and provides precise data about the target coordinates. The feed from the RADAR is integrated into the data fusion center for effective remote monitoring of the threats. The parameters of the flying object such as range, azimuth, and elevation are determined and plotted on an intuitive and user-friendly GUI.
VIDEO-BASED DRONE IDENTIFICATION & TRACKING (Optional)
The day and night camera sensors are mounted on an automatic servo-based positioning system. This system receives position commands from RFDD. Once positioned in the direction of interest, it captures video and images of the drone. VDIT is capable of capturing and tracking video. Video feeds are given to the software module, and video processing algorithms in the software automatically confirm the presence of the drone and initiate tracking.
DATA FUSION & COMMAND CENTER
This module integrates the data from RFDD, VDIT, and RADAR. Detection and classification algorithms based on all sensors are built into this system. An integrated display system enables the display of the threat situation. This display system integrates the map with zones of threat. Provisions to define the monitoring area, threat zone, and threat identification zone, among others, are available in the console. Spectrum and waterfall screens are also part of the software, providing a complete picture of the detected emissions.
DRONE RF JAMMER
Drone RF Jammer (DRFJ) can disable the link between GCC and Drone by jamming ISM bands, GNSS signals, and any other intercepted frequencies simultaneously. The frequencies detected by RFDD are automatically used to generate jamming waveforms, which are radiated using directional antennas. The system also supports user-configured frequencies to carry out the jamming action.
HARD KILL INTERFACE
Zen Anti-Drone System/Counter Unmanned Aerial System is offered with integration of Hard Kill options. Standard Air Defense Gun interfaces and a net-based drone catcher are the two options available. The gun interface can feed coordinates to the gun and align it to the target ingress direction to destroy it physically. Regulatory permissions required to use such solutions shall be obtained by the users. To capture the drone and land it at a safe place, a net-based drone capture option can be employed. For this, a dedicated drone with a hanging net could be launched to capture the rogue drone. This option is suitable for small rogue drones carrying potentially damaging explosives.
