Test method of UAV Detection and Early Warning Device and interpretation of related problems
2024-07-29
1. Suggested test method
1.1 Choose an open space away from the building, especially away from the camera with wireless map transmission, otherwise the detection and early warning device will detect the wireless map transmission signal to alarm(the same frequency as the UAV map transmission frequency) to generate misunderstanding;
1.2 The distance between the UAV and the flight controller should be far away, otherwise the remote control of the UAV has a high launch power, which will block the detection frequency band of the detection and early warning device;
1.3 The UAV generally approaches 3 kilometers from the detection and early warning device, and from the flight altitude of 150 meters to the direction of the detection and early warning device;
1.4 The FPV generally approaches 2 kilometers from the detection and early warning device, and from the flight altitude of 20 meters to the detection of the detection and early warning device.
2. Explanation of false alarm in UAV detection and early warning device:
At present, all the UAV detection and early warning devices on the market have the problem of false alarms, and the Interim Measures for Radio Management of Civil Unmanned Aircraft stipulates that the radio station of civil unmanned aircraft communication system that realizes remote control, telemetry and information transmission through direct communication shall use all or part of the following frequencies: 1430-1444MHz, 2400-2476MHz, 5725-5829MHz. These frequencies are public open, not regulated frequency bands, everyone can use it.
In addition to the drone remote control frequency, WiFi, bluetooth, wireless mouse, bluetooth technology, HomeRF technology, MESH, micro cellular technology also in 2.4G band frequency. In addition to the UAV remote control image transmission frequency, the wireless image transmission of various devices in the 5.8G band is used in this band, especially the urban security monitoring system, Skynet system is everywhere. In order to save costs, some locations use the camera wireless image transmission. Therefore, in the urban area, basically wireless map signal is everywhere, and our drone detection and early warning device detects the downlink wireless map signal of the drone, and false alarms are normal in the urban area, even in the suburbs or rural areas close to the residential location will be false alarms too.
The use scenario of the early warning device is used in the field for individual soldiers to warn the UAV, away from people, the surrounding wireless environment is relatively clean, there will be no other 2.4G and 5.8G signals, so there will be no false alarm.
In addition, it is often better to believe in the battle that it is not credible, and the alarm is timely to improve vigilance. If the drone does not come it doesn’t affect anything. If the relevant frequency is blocked, it will cause the missing report that the drone may not alarm, which will cause serious consequences. Just like the weather forecast, the principle is to report it will have rain or snow or storm while not report no, report big not small, there may be rain may be no rain, we take an umbrella in advance, there is rain is not drenched, no rain does not affect much.
3. Compared with the similar products on the market, our equipment has the advantages of:
3.1 long standby time, 4 hours battery life,can be charged with external batteries,can be charged with battery power bank, type-C interface, good compatibility;
3.2 good waterproof performance, for the harsh field combat environment, waterproof grade reaches IP67, that is, completely dust-proof, can work normally under the condition of immersion;
3.3 high reception sensitivity, receiver sensitivity-113 dBm, can realize UAV early waring be in a longer distance
3.4 Good environmental adaptability. It can work normally in an environment with 100% humidity at -30°C-55°C. Most detectors on the market are civilian type. Generally, it can work normally at low temperature-20 ° C. The performance of the environmental battery will decline sharply, the battery life will be greatly shortened, which will affect the use of equipment;
3.5 Simple operation, easy to use, all operations of the equipment with a button to complete, long press to switch on/off, double-click to display electricity, turn right to turn on the sound(clockwise), turn left to turn off the sound(counterclockwise).
