Lesson 27 — RAM, Polarization, and EMCON#
Shaping bought the orders of magnitude; this lesson buys the stubborn last decibels. Radar-absorbing material attacks the reflectivity knob, polarization betrays the edges and wires that shaping left behind, and emission control answers the one asymmetry no coating can absorb — the wave you chose to transmit.
RAM, Polarization, and EMCON
Quarter-wave cancellation and the narrowband promise, why polarization tells on edges and wires, and the intercept asymmetry that makes emitting dangerous.
