Effective Jam Power
Equation:  

  PJeff    =    PJ  x  GJ     (Watt)
Examble:

 PJ = 200 Watt
GJ = 6 dB (4)           

                                            200 x 4     =     800 Watt
  
If     BWR    < then   BWJ   then             PJeff    =    PJ  x  (BWR  /  BWJ)
If    BWR     > then    BWJ   then             PJeff    =    PJ   x  (BWJ  /  BWR)
   
BWR = Bandwidth Radar
BWJ = Jamming Bandwidth Jammer
PJeff = Effective Jamming Power
