Stats read the jammed radar. Fixed: P_tG_t = 90 dBW, B_r/B_j = −10 dB, burn-through at J/S = 10 dB, R_det = 100 km · (σ / 1 m²)^1/4. The SOJ's beam holds one victim radar; the other is unjammed, as in the Final Project. J/S = 4π·P_jG_j·R_t⁴ / (P_tG_t·σ·R_j²) · (G_r′/G_r) · (B_r/B_j), with G_r′/G_r = 0 dB within θ_B/2 of the jammer, else the sidelobe level.
