WERA HF Radar Software - Visualize Gridded Spectra

Plott_WERA16_Grid

Visualizes backscatter spectra processed by wera16_grid or wera16_grid_ol.
Reads all information needed from the header (first 512 bytes of data file).
The following box shows a typical output generated by Plott_WERA16_Grid: 

wera@ifmpc205:~/Fortran> Plott_WERA16_Grid ~/data/examples/20022921330_kna.spec
 Plott_WERA16_Grid V1.1.7 Linux:
 *** Now processing : /home/wera/data/examples/20022921330_kna.spec
 F_BRAGG    =  0.4087299 Hz

Graphics output can be generated for each selected grid point. The example shows a backscatter spectrum about 35 km off the WERA site at Kaena. Two strong first-order peaks can be seen with a slight shift to higher frequencies relative to the Bragg lines (in red). The second-order bands can also be identified left and right of the two first-order peaks. The peak at -0.75 Hz is probably due to a sailing ship. The horizontal red line markes the noise level.
