# Radar range eq notes (KINGFISHER)

R_max = [ Pt G^2 lambda^2 sigma / ((4pi)^3 Pmin) ]^(1/4)
4th root -> 16x power for 2x range. compact AESA, power-limited on a USV.
lean on coherent integration + low RCS surface targets are still detectable close in.

ISAR: target's own yaw/pitch/roll gives cross-range. needs dwell + motion.
classification from ISAR signature + length estimate. handoff to ALDER.
