CHAFF

 One CHAFF-UNIT (CU) = 50 sq. m

 500 gramme aluminium CHAFF for the


 F-Band (3 - 4 GHz)  consist of 1.37 million Chaff Dipols

 G-Band (4 -6 GHz)         "       2.05 million Chaff Dipols
 I-Band (8 - 10 GHz)        "      4.10 million Chaff Dipols

 

Quantity of Chaff Dipols to simulate a specific target

 

Equation: 

  N = ∆RCS    /    0.18 x λ
2
N                   = Number of Dipols needed
(delta)RCS    = to simulate Radar Cross Section (RCS)
λ                   = Wavelength (9.12 cm used in the example)
  Example 
            deltaRCS                  9.122

N    =    100    /    (0.18 x 0.0083266)    = 66 720 Dipols
are needed to simulate a target having a RCS of 100m2.
