Novel method for angle estimating of bistatic MIMO radar
The extended signal subspace was constructed to reduce the computation load of former data processing of bistatic MIMO radar.According to the characteristic of this signal subspace,the polynomial rooting-spatial filtering algorithm was proposed to estimate the direction of arrivals (DOA) and directi...

| description | The extended signal subspace was constructed to reduce the computation load of former data processing of bistatic MIMO radar.According to the characteristic of this signal subspace,the polynomial rooting-spatial filtering algorithm was proposed to estimate the direction of arrivals (DOA) and direction of departure (DOD).It avoided the conventional two-dimensional spectrum searching and the estimated parameters were paired automatically without extra pairing operation.Furthermore,Cramer-Rao bounds (CRB) for DOA and DOD estimation were derived under multi-target and single target in bistatic MIMO radar.The results illustrate that when spatial sector is filt the higher order of the Taylor series expansion,the better angular accuracy of targets can be derived.The proposed algorithm can get good estimation performance even when the DODs of targets are close to each other.And the polynomial rooting-spatial filtering algorithm can perform better than ESPRIT algorithm in resolution in SNR,and both of them are close to the CRB in the high SNR. |
