M. Grecu et We. Krajewski, An efficient methodology for detection of anomalous propagation echoes in radar reflectivity data using neural networks, J ATMOSP OC, 17(2), 2000, pp. 121-129
To detect anomalous propagation echoes in radar data. an automated procedur
e based on a neural network classification scheme has been developed. Earli
er results had indicated that algorithms used to detect anomalous propagati
on must be calibrated before they can be applied to new sites. Developing a
calibration dataset is typically laborious as it involves a human expert.
To eliminate this problem, an efficient methodology of calibrating and vali
dating neural network-based detection is proposed. Using volume scan radar
reflectivity data from two WSR-88D locations, the authors demonstrate that
the procedure can be calibrated easily and applied successfully to differen
t sires.
