Electronic Attack (EA) / Jamming

P3: Expert

Electronic Attack (EA) / Jamming

1. Conceptual Intuition (L1)

  • The "Cocktail Party" Problem (Shouting louder than the other person).
  • Noise Jamming (Brute force) vs Deception Jamming (Lying).
  • Frequency Hopping to escape jamming.

2. Engineering Math (L2)

  • Jamming-to-Signal Ratio (J/S).
  • Burn-Through Range (RbtR_{bt}): When radar power > jammer power.
  • Processing Gain implications (PG=BWRF/BWinfoPG = BW_{RF} / BW_{info}).

3. System Application (L3)

  • DRFM (Digital Radio Frequency Memory) basics: Record and replay.
  • Range Gate Pull-Off (RGPO).
  • Low Probability of Intercept (LPI) waveforms.
