[0026] The present invention will be further described below in conjunction with the accompanying drawings.
[0027] A MIMO radar imaging method under the condition of array element failure,
[0028] Step 1: Establish a non-uniform sampling MIMO radar echo signal model under the failure of the array element;
[0029] 1a. Assume that the centralized MIMO radar has M t transmit antennas and M r receiving antennas, M t The transmit signal waveform matrix of an antenna is
[0030]
[0031] where x m =[x m (1), x m (2),...,x m (L)] T Represents the transmitted signal of the mth transmitting antenna; L is the length of the transmitted signal;
[0032] 1b. Divide the target scene area into P distance units, K angle units and H Doppler units; then the target scene area is divided into D discrete distance-angle-Doppler units {(τ p ,θ k ,ω h )}, D=P K H, where 1≤p≤P, 1≤k≤K, 1≤h≤H;
[0033] 1c. Suppose the h-th Doppler unit is denoted as ω h , then define the signal corres...
