The distance between the Victim link receiver and the Interefering link transmitter is referred to as the simulation radius (see ANNEX 13:). It can be defined as shown in Figure 121.

Figure 121: Definition of the minimum distance

Using this feature, the interefering link transmitter is located between 1 km (0.1 x 10 km) and 10 km (1 x 10 km) from the Victim link receiver as shown in the SEAMCAT display in Figure 122.

If the interefering link transmitter is located at 10 km, it is possible to derive the iRSS_unwanted:

iRSS_unwanted = 33 (dBm) + 11 + 9 - (32.5 + 10 log(10 x 10) + 20 log(1000))        

iRSS_unwanted = 53 - 32.5 = 20.5 - 60 - 20 = -59.5 dBm                                      

If the interefering link transmitter is located at 1 km:

iRSS_unwanted = 33 (dBm) + 11 + 9 - (32.5 + 10 log(1) + 20 log(1000))     

iRSS_unwanted = 53 - 32.5 = 20.5 - 60 = -39.5 dBm                         

The iRSS_unwanted extends from -59.5 dBm to -39.5 dBm as confirmed by Figure 123.
