UAV detection radar manufacturers believe that according to the working principle of the radar, regardless of the frequency of the transmitted wave, it belongs to the radar system to detect and locate the target by radiating electromagnetic energy and using the echo reflected by the target.
UAV detection radarThe manufacturer believes that according to the working principle of the radar, regardless of the frequency of the transmitted wave, the radar system uses the echo reflected from the target to detect and locate the target by radiating electromagnetic energy. The operating frequency range of common radars is 220 MHz to 35,000 MHz. In fact, the operating frequency of various radars is beyond the above range at both ends. For example, the operating frequency of the OTH radar is 4MHz or 5MHz, while the operating frequency of the OTH radar is as low as 2MHz. At the other end of the spectrum, millimeter-wave radar can operate up to 94GHz, and lidar can operate at higher frequencies. The radar with different working frequency varies greatly in engineering realization.
UAV detection radarManufacturers believe that the main technical indicators of radar:
1. Antenna feeder function
Antenna aperture, antenna gain, antenna lobe width, antenna beam sidelobe level, polarization form, feeder loss and antenna feed system bandwidth.
2. Radar signal form
UAV detection radar manufacturers believe that the form of radar signal mainly includes working frequency, pulse repetition frequency PRF, pulse width, pulse train length, signal bandwidth, signal modulation form, etc.
3. Transmitter performance
The transmitter performance mainly includes the peak power, the average power, the total gain of the power amplifier chain, the final efficiency of the transmitter and the total power of the transmitter.
4. Receiver performance
UAV detection radarThe manufacturer believes that the receiver performance mainly includes receiver sensitivity, system noise temperature, receiver operating bandwidth, dynamic range, intermediate frequency characteristics, etc.
5. Angle measurement method
UAV detection radar manufacturers believe that the test methods are mainly divided into amplitude method, phase method and antenna beam scanning method.
6. Radar signal processing
System improvement factors for moving target display and moving target detection, pulse Doppler filtering implementation and computing speed requirements, constant false alarm rate processing and video accumulation methods.
7. Radar data processing capability
Target tracking ability, secondary solving ability, data conversion and input/output ability.
UAV detection radarThe manufacturer believes that in the modern air transportation system, it is necessary to strictly control the aircraft around the airport and on the route. Air traffic control radar has the functions of both warning radar and guidance radar, so it is sometimes called airport surveillance radar and is used together with secondary radar. The ground equipment of the secondary radar transmits an inquiry signal. After receiving the signal on the aircraft, it sends a response signal in the form of a code. After receiving it on the ground, it is displayed on the display of the traffic control radar.
UAV detection radarThe manufacturer believes that this radar system can identify air targets by identifying their altitude, speed and attributes. Some kind of radar installed on satellites or aircraft can be used as a microwave remote sensing device. Feel the main geophysical information. Thanks to its two-dimensional high resolution, it can measure and map topography, water resources, ice sheets, agricultural forests, geological structures and environmental pollution.
