Embodiment Construction
[0021] refer to figure 1 , the specific implementation steps of this embodiment are as follows:
[0022] Step 1, according to the element distribution of the monostatic MIMO radar, obtain the steering vector A(θ) of the matrix.
[0023] According to the array element distribution of monostatic MIMO radar, the polar coordinates of each array element are obtained as (r n ,β n ), n=1,2,...N, N is the number of array elements;
[0024] According to the polar coordinates of each array element (r n ,β n ), get the transmit steering vector a of the MIMO radar t (θ) and receiving steering vector a r (θ) are respectively:
[0025] a t ( θ ) = [ e jk r 1 cos ( ...
