Abstract :
Pointing and scanning control algorithms for a two-axis gimbal, inertially stabilized, airborne antenna system are described and evaluated computer simulation. Satisfactory performance is demonstrated in the presence of aircraft maneuvers, with some (expected) degradation for the very-near-zenith antenna states. The antenna scanning algorithm presented is adaptive in its scan rate (to avoid scan distortions due to azimuth rate limiting imposed by the physical antenna system), is simple to implement, and properly accounts for aircraft maneuvering to maintain circular scanning trajectories in inertial space.<>
