An Adaptive Multi-Beamforming Algorithm for Electronic Reconnaissance |
|
() |
Abstract: |
An adaptive - adaptive multi - beamforming algorithm for electronic reconnaissance is introduced and proved. The algorithm estimates the direction and amount of space source first, and then synthesizes the pattern. It is shown from simulation results that jamming cancellation performance is significantly improved by using this algorithm. |
