System Overview:

BM-200 single polarization fully coherent Doppler weather radar. It uses Doppler radar technology to obtain data such as distance, azimuth, reflectivity, and target speed, controls the radar work through software, and processes the obtained basic weather data to generate meteorological products. The BM-200 radar can realize the monitoring and forecasting of conventional and severe weather phenomena.

System composition:

BM-200 single polarization pulse Doppler weather radar consists of antenna and servo system, transmitting system, receiving system, monitoring system, signal processing system, product generation and display system, power distribution system and accessories.

Features:

The system has automatic, safe, continuous, stable and reliable, and unattended operation capabilities. Each subsystem and module is produced, debugged and inspected in strict accordance with technical specifications. All modules that have nothing to do with frequency between systems are interchangeable.

The high-reliability radome against super typhoon is selected, which has been verified by hundreds of systems at home and abroad for many years.

Antenna drives use maintenance-free and long-life AC motors (domestic weather radar antennas usually use brushed DC motors that require maintenance twice a year and have low reliability).

When collecting data, the antenna speed control system uses automatic tracking and adjustment technology, which effectively ensures the spatial positioning accuracy of the detection data.

The klystron is selected from CPI company with a working time of more than 80,000 hours, a working frequency that can be selected by the user within 2700MHz to 3000MHz, and a peak power of 800KW. This not only improves the radar detection capability, data quality, radar applicability, stability and reliability, but also brings great benefits to maintenance and spare parts purchase and storage.

The absorbing active PIN tube receiver protector with long life, low noise, high isolation and fast response is selected, which effectively avoids the influence of the protector on the transmitted pulse and ensures the actual coherence performance of the system.

The high-precision and large-range imported radio frequency numerical control attenuator is used to ensure the reliability and accuracy of the online calibration branch.

It has the functions of real-time online automatic calibration, safety self-protection and multiple fault monitoring points, which effectively guarantees the objectivity and accuracy of the detection data and the safety of the equipment.

It has the network function of sharing observation data and products with multiple weather radars in real time, and has been successfully used in the Beijing Olympic Games, the 60th anniversary celebration of the founding of the People's Republic of China, the 11th National Games and the 2010 Shanghai World Expo.

The system reserves the space, machinery and installation interface required for dual-linear polarization upgrades, without replacing or discarding any components, and only needs to add relevant components to complete the upgrade of dual-linear polarization at the radar station.
