|
electronic support
|
|
|
give the definition of Electronic Protection.
|
actions taken to protect personnel, facilities, and equipment from any Electroonic Warfare employment tht may degrade, neutralize, or destroy friendly combat capability.

nic Warfare employment tht may degrade, neutralize, or destroy friendly combat capability. |
|
|
what is the most permanent countermeasure to Electronic Warfare ?
|
destruction
|
|
|
describe the QRC (quick reaction capability) program.
|
it is a program desgned to rreuce the time interval between recognition of a new threat and establishment of an operational capability to cope with it
|
|
|
name three ways a jamming transmitter may jam a radar.
|
1. blocking radar receiver with high concentrated power
2. masking some or all targets appearing on the radars indicator 3. creating many false targets |
|
|
what type of jamming has a bandwith approximately that of the victims radar ?
|
spot jamming
|
|
|
how do we classify sweep jammers ?
|
slow and fast, depending upon the rate at which the jamming signal is swept over its frequency band
|
|
|
what type of jammer is designed to put fallse targets on the radar screen?
|
repeater jamming
|
|
|
what do mechanical jammers consist of ?
|
all Electronic Attack devices that do not radiate electromagnetic energy . secifically reflecting , absorbing, and destruction devices.
|
|
|
how does chaff act as a mechanical jammer ?
|
the reradiating efficiency of chaff is greately increased when the individual strips are cut to half a wavelength of the victims radar efficiency
|
|
|
name the three basic types of chaff .
|
1.continuous
2.random 3 burst |
|
|
what factors affect chaff's screening ability ?
|
-eveness of dispersal
-relative density -the degree to which the particular chaff type reonantes at the given radar |
|
|
explain the use of flares.
|
they are used as a counter measure for IR receivers aboard interceptor aircraft or against an IR-seeking missile
|
|
|
wh are the operators the most critical elements in an EP proogram ?
|
the operatorsmust know how and when to use the different EP features of their equipment and realize how those features will affect the radars performance
|
|
|
what are fixes ?
|
term used to describe features designed into a radar system or modifications to existing systems that degradeor eliminate the effectiveness of EA
|
|
|
define Frequency Agility.
|
the ability of a radar set to rapidly tune from one frequency to another frequency
|
|
|
against what type of jammer is frequency agility the most successful ?
|
a manually tuned sot jammer
|
|
|
what is diplexing ?
|
the use of 2 seperate trqansmitters and/or receivers operating on different frequencies but using a common antenna systeem
|
|
|
describe some of the effects EP may have on the system employing it.
|
the use of EP may degrade the ability of a radar by limiting its range or reducing its sensitivity. to help them reach their taret system, degredations can be exploited by penetrating forces.
|
|
|
what is one thing that you must not do whenreporting EA ?
|
do not mention anything about EA over unsecured radios or telephones
|
|
|
how do you use triangulation to determine the location of a jammer ?
|
the intersection of 2 or more rdar EA strobes to determine the position of the jammer
|
|
|
how can you best describe spark jamming ?
|
most simple and primitive type of jamming. its when something electronic is nect to a television because it is so primitive it is easy to generate.
|
|
|
why is sweep-through jamming so widely used ?
|
it is easy to produce
|
|
|
what does stepped-tone jamming sound like ?
|
the wail of bagpipes
|
|
|
why is noise jamming so dangerous ?
|
because the operater can mistake it for receiver or atmospheric moise and become jammed without even noticing it.
|
|
|
list some of the general rules that help you in combating jamming.
|
-keep operating
-keep your temper -continue to handle traffic no matter how difficult -consider all interference unless you can otherwise -pass traffic by alternate means available(different frequencies,different types of antennas, etc) |
|
|
if faced with severre jamming on all frequencies, which frequencies can you use as a last resort and under what condition?
|
use the enemy's frequencies
|
|
|
why is it important never to reveal over the air that you are experiencing jamming ?
|
it lets the nemy know they have succeeded
|
|
|
what directive provides directioin and guidance concerning EMI reporting ?
|
Air Force Spectrum Interference resolution program
|
|
|
what is the preferred way of submitting EMI reports ?
|
via electronic message
|
|
|
how soon must you submit an initial report on an EMI incident ?
|
within 24 hours
|
|
|
what are the 3 types of reports that you can make during and EMI incident ?
|
1. initial
2. supplement or follow-on 3.closing |
|
|
what does a supplement EMI report contain ?
|
when you need to add modify information already submitted you may also use it request EIG ( engineering installation group) technical assistance
