Q

Objective of EA

A

Deny/Delay:

  • Detection
  • Identification
  • Tracking
  • Kill Chain / Decision Making

Increase threat weapon miss distance

Attack the Kill Chain, Buy Time

Q

List 4 types of deceptive jamming

A

Standoff/escort
- IADS-level deception

Transponder

  • Preprogrammed techniques that jam signals in response to:
  • Reception of a threat pulse signal
  • Predicted reception of a threat pulse signal

Repeater
- Techniques that alter and retransmit actual received signals

DRFM
- Most advanced, fielded EA technique generator used to defeat PD radars

Q

What is DRFM (Digital Radio Frequency Memory)

A

Incoming threat radar signal processed and stored in digital memory
- At will, the DRFM jammer recalls this signal, modulates, amplifies and transmits the signal

Q

What is the most critical factor in S/N or J/S? (Footstomp)

A

Range

17
Q

Radar S/N considerations

A

Two-way Trip - radar to target and back

- S/N calculated based on R^4

18
Q

Communications S/N considerations (Footstomp)

A

One-Way Trip - Transmitter to Receiver

- S/N calculated based on R^2

19
Q

3 characteristics that effect jamming quality

A

Jamming signal must emulate the victim signal characteristics

#1 Frequency
#2 Polarization (method of travel)
#3 Coherent vs noncoherent (PRI or phase)
