What is a "Jamming Signal Ratio"? The Most Authoritative Explanation.
What is the formula for jamming to signal?
JAMMING TO SIGNAL (J/S) RATIO - CONSTANT POWER [SATURATED] JAMMING The following table contains a summary of the equations developed in this section. JAMMING TO SIGNAL (J/S) RATIO (MONOSTATIC) J/S = (Pj G ja4B R ) / (P t G t F) (ratio form)* or: 2
How to reduce the J/S of a jamming signal?
C If the frequency of modulation is greater than the BW of the tracking radar reduce J/S by 20 Log (duty cycle). For example; if your jamming signal is square wave chopped (50% duty cycle) at a 100 Hz rate while jamming a 1 kHz bandwidth receiver, then the J/S is reduced by 3 dB from the maximum.
What is the J/S ratio for jamming?
J-S Ratio (Monostatic) The ratio of the power received (P r1 or J) from the jamming signal transmitted from the target to the power received (P r2 or S) from the radar skin return from the target equals J/S. Note: To avoid having to include additional terms for these calculations, always combine any transmission line loss with antenna gain.
How does jamming affect wireless communication?
Depending on the power of the radio transmitter and location and influence of the jammer on the network, jamming can cause significant disruption in wireless communication. How do jamming attacks work?
