Weather Radar Calibration System

With innovative calibration technology, obtaining reliable high-quality weather radar data in a cost-effective way becomes feasible. The Swiss made dual-polarization radar target simulator, specifically developed for the needs of the weather radar community, generates radar targets with unprecedented accuracy.
High-precision radar target simulator is able to quickly generate a virtual reference target with pre-defined Doppler, range and polarimetric character-istics. In addition, every individual radar pulse can be logged, leading to a complete weather radar test suite for the measurement of pulse widths, phase and frequency, antenna pattern, Doppler properties, pointing etc.
Off-the-shelf transceiver hardware is combined with specifically engineered dual-polarization HF front-ends. Received radar signals are downconverted over several stages, digitized, modulated, delayed and retransmitted in perfect correlation to the desired virtual target properties.

Feature:


•Selectable and calibrated radar cross section and Doppler velocity
•Selectable and calibrated dual-polarization target properties (Zdr,
•High Doppler (0.1 ms-1 ) and reflectivity (0.5 dB absolute, 0.2 dB differential) accuracy
•Control via graphical user inter-face
•Comprehensive pulse analysis capability
•Portable and outdoor proof
•Optional radiometer capability

•Currently tested for X-band, C- and S-band under development
