SRT beam patterns at C-band (7.24 GHz, left-column panels) and K-band (right-column panels) respectively. For K-band we show only the 25.54 GHz measurement of the central beam. Top: elevation-averaged beam patterns (normalized to a peak value of 1) obtained by stacking together several OTF scans of bright point sources taken at different elevations. The color map has been intentionally saturated to highlight the low intensity features of the second and third lobes. Bottom: beam cross-sections along the azimuth and elevation axes (in dB).
