An adaptative array processor using the analog L.M.S. algorithm: An efficient solution for a N.A.V.S.T.A.R./G.P.S. application
A study has been performed to demonstrate the efficiency of adaptive signal processing for NAVSTAR/GPS (Global Positioning System) signal reception in a jamming ECM (electronic countermeasures) environment. The role of an adaptive antenna for such a system is to increase the signal to noise plus interference ratio (SNIR) to a power sufficient for most commercially available GPS receptors. The GPS signal reception power is about -160 dBm at the antennas. The analog LMS (least mean square) algorithm has been chosen for its highspeed/simplicity and lowcost trade-off. Test show good results: 64 dB SNIR enhancement in less than 300 /spl mu/s. Practical implementation of the LMS algorithm leads to experimental results that agree with the numerical simulation predictions.<>
