A Robust Sidelobe Cancellation Algorithm Based on Beamforming Vector Norm Constraint

Algorithm 1

Robust SLC algorithm.

Step 1: Compute and .

Step 2: Use Equation (5) to calculate (unconstraint SLC). If , go to Step 5; otherwise, go to Step 3.

Step 3: Compute the eigendecomposition of .

Step 4: Use Equation (22) to find optimal by numerical search.

Step 5: Use Equation (17) to calculate .

Step 6: Use Equation (3) to calculate SLC output signal.
