Sensors

Detection equipment, grouped by propagation medium. A component with more than one detection mode carries one specification group per mode.

Representative detection ranges are free-space figures against a named reference platform. Sensors covers the propagation effects — horizon, clutter, Doppler notching, thermocline and convergence zones — that reduce them in practice.

ID — identification capability. Radar resolves contact affiliation by IFF transponder interrogation; visual and acoustic receivers resolve identity through signature analysis.

Sensitivity — RF receivers (radar, RWR) are rated in dBW; infrared, visual, and acoustic receivers are rated in dB referenced to a standard target signature.

A range shown with a trailing + means the receiver holds that reference platform anywhere in the operating area — the figure is the width of the area, not a limit of the equipment.
