DWSR 5001C

The DWSR 5001C is a C-band dual-polarization precipitation radar. It is a further development of the DWSR 2501C by doubling the power of the transmitter (2×250 kW) and the number of receivers so that the radar can transmit simultaneously in linear-horizontal and linear-vertical polarization (so-called STAR- Mode: Simultaneous Transmit Alternating Receive). The radar can be completely remote controlled. It is a standard device of the Deutscher Wetterdienst (German Weather Service) and has replaced the older Meteor 360.

The receiver is located in one of the boxes on the antenna, so that line loss or loss due to a slip ring unit are avoided. The transmitter, power supply, and synchronization blocks are located in a two-door rack in the operating room under the radome. The transmitting power is conducted to the antenna by a waveguide. The operating room also houses the computer workstation from which the radar can be operated locally and where the local composite radar products are calculated. These, as well as the raw data, are transmitted via a secure transmission interface to the network of the German Weather Service.

The magnetron is over-dimensioned and easily copes with the different loads caused by the dynamically applied different pulse repetition frequencies. The integrated BITE system of the radar is able to monitor about 1500 different parameters, some of which, however, have been recognized as irrelevant and deactivated by the user. Regular maintenance is essentially reduced to mechanical checks. Only the calibration of the radar has a special meaning, it is controlled from the computer workstation.
