dual_dop - Dual Doppler lobes
The dual_dop package draws regions where Doppler data from two radars can be synthesized into a complete wind field. For information on the rationale and calculations, consult Davies-Jones, Robert P., Dual-Doppler Radar Coverage Area as a Function of Measurement Accuracy and Spatial Resolution, Journal Of Applied Meteorology, 18, 1229,1233
The hatched region shows where beams from a pair of radars cross by at least a given angle, and within the radars' nominal ranges. Radar positions and ranges can be entered explicitly. The radars can also be dragged with the mouse. You can draw any number of radar pairs in any number of maps. For complete details, consult the run-time help or the man page.
The dual_dop package is part of the visky base distribution.
