Abstract:
The major advanced features and performances of Shanghai imported mobile Xband dualpolarized Doppler weather radar system have been described in this paper. Detailed analysis and comparisons of the radar specifications and the technical measures adopted between the imported mobile radar and the same domestic type have also been conducted in order to indicate that these super specifications and technical measures realized already in the import one are necessary and important for obtaining better qualitybased dualpolarized parameters, such as ZDR, KDP,ΦDP, ρHV etc. All those mentioned above in the imported weather radar include 200 kW peak power output, over 40 dB averaging ground clutter suppression in the IF coherence system, 95 dB to 100 dB receiver linear dynamic range and ≤-112 dBm receiver sensitivity (1 μs pulse width), with the finest 31.25m range bin resolution, innovated and patented antenna mounted receiver (AMR) technique, as well as integrated EDGE5.0 software package providing varieties of radar products. It has also illustrated some images acquired by this mobile radar from the field observation. The paper indicated finally that all the advanced aspects achieved in this imported mobile radar are worthy to be learned and followed by domestic weather radar manufacturers.
