Figure 37. 



-Ray diagrams illustrate the expected subnormal propagation conditions 

 on the Grand Banks as compared to "standard" conditions for both 

 S- and X-band radar. Top standard diagram is superimposed on bottom 

 diagram to illustrate the difference in lobe pattern between the two 

 conditions. It may be inferred from these diagrams that little change in 

 field strength is to be expected within the first 8(100 yards from the 

 antenna.
