A robust algorithm for passive angle tracking of multiple moving targets

The performance of MUSIC [Schmidt, 1979], Sastry's [Sastry et al., 1991], Sword's [Sword et al., 1990] and the like algorithms degrade rapidly in the absence of a perfect array geometry that introduces phase errors in the received data covariance matrix. In the present paper, a stable high resolution (SHIRE) algorithm, assuming no perfect array geometry for the receiving sensors, has been developed and applied to solving this class of passive multiple targets angle tracking problems. Computer simulation results demonstrate that good tracking performance is achievable by the SHIRE algorithm.<
