Null steering bistatic mimo radar
Web25 nov. 2024 · For MIMO radars that emit non-orthogonal waveforms, the transmit steering vector cannot be used to estimate the DOAs of targets when the waveform correlation matrix is unknown. The maximum number of targets that can be estimated by our approach depends on the rank of the covariance matrix and the angle estimation method. WebThis gives an enlarged virtual receive aperture. Multiple-input multiple-output (MIMO) radar is an advanced type of phased array radar employing digital receivers and waveform …
