Glossary

AOB: All-in-One Board — a fully integrated architecture combining TR, waveform control, and power management on a single board.

Conformal Design: Antenna array shaped to match the curved surface of an airborne platform (e.g., aircraft fuselage), minimizing aerodynamic drag.

EIRP: Effective Isotropic Radiated Power — the power transmitted by an isotropic antenna to produce the same signal strength.

G/T: Figure of Merit — ratio of antenna gain to system noise temperature, indicating receive performance.

Circular Polarization: Polarization where the electric field vector rotates in a circle; includes RHCP (right-hand) and LHCP (left-hand).

TNC: Threaded Neill-Concelman connector — a threaded RF connector rated up to 18 GHz (some variants higher).

Micro-D: A miniature D-sub connector series widely used in aerospace and military applications.

MDM: Microminiature D connector series (e.g., MDM-25S = 25-pin socket), conforming to MIL-DTL-83513.

J30JY: Chinese national defense standard (GJB) micro rectangular connector series with latching mechanism.

Inertial Navigation Interface: Connection to an INS (Inertial Navigation System) providing real-time attitude data for beam pointing correction during flight.
