Literature Review Electronic warfare

Homemade devices, made from readily availablecomponents. These include fertilizer bombs andfire bombs [1]

Radio controlled systems involve using an RF

device to initiate a device[1] The RCIED device contains a radio receiver with

the commander having a correspondingtransmitter to trigger the device[1]

also be within range ofthe receiver[1]

Methodology Three types of jamming technique can be used

when we will implement our jammer in denialof service domain(dos).

Swept spectrum jamming[3]

Intelligent spot jamming[3]

Barrage Jamming[3]

MethodologySwept spectrum jamming It is the jamming technique that can be explained in

which the carrier frequency is not noise modulatedbut swept over the frequency ranges[3]

It is not necessary to know the exact frequency ofradio trigger ahead of time[3]

The sweep rate must be very fast in order to re-visitall the frequencies within the swept time[3]

MethodologyIntelligent spot jamming

This effective technique, but only when the

frequency of radio trigger is known in advance[3]Barrage Jamming

This technique overcomes the problem of notknowing the operating frequency of radio trigger

used to detonate the IED[3] It is effective against low-powered transmitter and

narrow band frequency ranges[3]

Distances (continued)

However, the Bomb Jammer VIP Systems have beentested against multiple threats at controlled distances andoutput powers[3] Demo

As previously stated, no distance canbe guaranteed as a result of multiple

factors which are beyond control[3]

J = the jammer signal strength to thereceiver (dBm);

ERPJ= the jammer effective radiatedpower (dBm);

F = the communication frequency (MHz)

GRJ= the receiving-antenna gain in thedirection of the jammer (dB);

dJ= the range from the jammer to thereceiver (km)

S = the desired signal strength to thereceiver (dBm);

ERPs = the desired transmitter effectiveradiated power (dBm);

F = the communication frequency (MHz);

GRS = the receiving antenna gain in thedirection to the desired signa transmitter(dB);

Expected Results & Discussion

It is expected that the range from 25MHZ to3000MHZ signal will be jammed if the triggeringsignal frequency will be in this range

Discussion

We will prefer DOS because Swept CW (Continuous Wave) is ajamming technique that can be explained in which the carrier

frequency of the jamming is not noise-modulated, but onlyswept over the frequency ranges that correspond to the bandsthat could be used by radio triggers. In this technique, theexact frequency of the radio trigger does not have to be knownahead of time.

If the band is relatively narrow, then the carrier neednot be modulated to still be effective in jamming thereceiver. However, this is usually not the case, and

therefore, the jamming effectiveness of swept CW isgreatly diminished when deployed over a widebandwidth
