Angle Estimation Using Local Searching for Bistatic MIMO Radar with Unknown MCM
Algorithm 1
The proposed method.
1: Use MUSIC with AS method, find the initial angle estimation .
2: Define a local search range , divide and into S +1 segments, obtain (S +1)2 angle points to be estimated.
3: Compute the mutual coupling matrix C and the transformation matrix T according to (6) and (8)–(12), respectively.
4: Using noise covariance matrix and T obtained in step 3, compute according to for each angle point.
5: Compute the eigen decomposition of .
6: The angle point corresponding to the minimal eigenvalue obtained from step 5, which is select as angle estimation of the qth target according to (15).
7: Obtain the mutual coupling coefficients according to (16).
