Abstract :
An algorithm for high-accuracy estimation of angle and frequency in MIMO radar is presented. Multi rotational factor, which is produced by smoothing of the temporal samples, is exploited to estimate the Doppler frequencies of targets. By utilizing multi-ESPRIT and joint-diagonalization, the accuracy is improved. The direction of arrivals (DOAs) can be obtained by means of a generalized weighted linear predictor (GWLP) estimator. Comparative simulations are provided to verify its effectiveness and superiority.
