L7 Pre-flight#

Block 1: Radar Fundamentals — Lesson 7: Threat Radar Taxonomy in an IADS Work this before L7. Pre-flights are never collected — in class, anyone may be cold-called to present any question at the board, and that recitation is the participation grade.


Assumed pre-class reading#

  • L6 wrap-up

  • The Jupyter Book Reading page for L7 — IADS Radar Taxonomy — which lists EW / ACQ / HF / GCI / TTR / AI / TIR / seeker / fuse with their typical bands, PRF regimes, beams, and roles.


Quiz questions (5 items, ~5 minutes)#

Q1. (Multiple choice) An IADS Early Warning (EW) radar typically operates at:

  • [ ] (a) Ka-band, high PRF

  • [ ] (b) UHF or L-band, low PRF

  • [ ] (c) Continuous wave, X-band

  • [ ] (d) mmW, very high PRF


Q2. (Multiple choice) Which radar class is most commonly used as the SAM site’s fire-control sensor (TTR)?

  • [ ] (a) UHF surveillance radar

  • [ ] (b) X-band pencil-beam pulse-Doppler radar

  • [ ] (c) Ka-band continuous-wave illuminator

  • [ ] (d) mmW proximity sensor


Q3. (Multiple choice) A Target Illuminating Radar (TIR) supports which kind of missile guidance?

  • [ ] (a) Active radar homing

  • [ ] (b) IR homing

  • [ ] (c) Semi-active radar homing

  • [ ] (d) GPS-aided inertial


Q4. (Short answer) In one sentence, why does LO buy the most absolute kilometers of range reduction at the EW / ACQ layer rather than at the engagement layer?


Q5. (Multiple choice) You intercept a CW emission at 10 GHz that is paired with a different pulse radar nearby. The most likely class is:

  • [ ] (a) Active missile seeker

  • [ ] (b) Target illuminating radar (TIR)

  • [ ] (c) Early warning radar

  • [ ] (d) Proximity fuse
