5KM Drone Detection & 3KM jammer&Navigation signal simulation system
1、 Profile
This product is used for UAV detection, identification and jamming ,Navigation signal simulation system. has the advantages of easy deployment, mobile compatibility, early warning and positioning with trajectory tracking. When a drone enters defense area, this device can raise the alarm, determine the real-time location of the target and the pilot through CRPC message-level protocol cracking, and record the trajectory of the UAV, also can jamming if need.
Use cognitive radio protocol reverse parsing technology which uses radio spectrum sensing technology (similar to the feature extraction of viruses by Internet antivirus software) to extract UAV communication signals (mainly remote control and image transmission signals) from background noise and conduct in-depth reverse parsing of them.
Through offline analysis of UAV communication protocols and extraction of features (electronic fingerprint ID), including but not limited to channel distribution, modulation scheme, coding scheme, pilot sequence, synchronization sequence, link layer structure, etc. Based on the above analysis results, a UAV detection database is formed, and matching is detected in real time in the actual radio environment. Finally, features are applied to real-time detection (feature fast matching recognition) and precise strike (distinguishing different UAVs for strike) of UAVs.
Navigation signal simulation suite is based on navigation satellite signal simulation technology which simulate and generate various types of navigation satellite signals, including GPS, Glonass and BDS. Both static and dynamic signals can be simulated, and it is suitable for simulation test for all kinds of navigation receivers and terminals, test for full scene verification, positioning, timing and dynamic performance evaluation. It can also be used for anti-jamming antenna and receiver test in a closed environment and other application scenarios.
