Abstract:

To solve the problem of scattering coefficient estimation of the target observed by multiple angles, the parameter estimation method based on distributed compressed sensing (DCS) is investigated for transmit diversity multiple-input multiple-output (MIMO) radar. The signal model of the transmit diversity MIMO radar is analyzed and its joint sparse representation model is constructed correspondingly. Based on analyzing the realization construction of the orthogonal matching pursuit (OMP) algorithm, a new DCS algorithm is proposed by using iterative OMP method. Simulation results show that the proposed method has a better accuracy than the DCS-SOMP and amplitude phase estimation (APES)+Capon algorithms and higher reconstruction probability than the DCS-SOMP algorithm.
