Abstract
Algorithms for an adaptive antenna system are developed to estimate the direction of arrival for multiple signals to reduce spatial search. The system works in conjunction with a frequency hopping modem to minimize average acquisition time while improving the signal-to-interference-plus-noise ratio at the modem input. Simulation results indicate that an adaptive antenna can optimize acquisition time and estimate signal direction simultaneously in the presence of interference.<>
