Punta Salinas blanking sector




    Punta salinas blanks their radar in the AO direction. Back in 2006 we did a test with them checking various blanking sector widths. Prior and after this test, the blanking region was set to 90 degrees ( +/- 45 degrees in the AO direction).
     In nov13 I noticed that the blanking had been changed to 22 degrees. Using a2130 data  i searched back to see when the blanking changed.

The plots below show total power vs time for the mode A frequencies of  punta salinas (1232.8,1242.2,1248.9, 1257.0). 1.3 Mhz about each radar frequency was used.
