This blind adaptive interference rejection algorithm aims to null multiple smart jammers and background clutters impinging from unknown azimuths and elevations using a sensor array with unknown or uncalibrated array manifold. This algorithm, by exploiting the Doppler diversity and delay diversity amongst the desired signal and interferences, separately estimates the spatial correlation matrix (RI+N) encompassing only the interference and noise and the spatial correlation matrix (RS+I+N) encompassing the desired signal plus interferences and noise. The eigenvector corresponding to the largest generalized eigenvalue of the matrix pencil pair {R+I+N,RI+N} represents the optimum adaptive beamforming weight vector w° that will maximize the signal-to-interference-plus-noise ratio (SINR). This alternate ISR (intelligence/surveillance/reconnaissance) technology could lower the cost and may enhance the reliability of existing sensor-array adaptive beamforming technology in pulse radar systems, in military and commercial Global Positioning System (GPS) navigation devices, and in UAV electronic surveillance systems.
