Necessary Bandwidth Calculation

The necessary bandwidth was determined using the equation in Annex J of the NTIA Manual1
for FM-CW radars (see Equation 1). The ELTA EL/M-2112 emission has a maximum
frequency deviation of 25 MHz. Applying this frequency to Equation 1 yields a necessary
bandwidth of 50 MHz.

Bn = 2Bd (1)

where

Bn = necessary bandwidth, MHz
Bd = frequency deviation bandwidth (peak difference between
modulated wave instantaneous frequency and carrier frequency for
FM/CW radar systems, MHz
