A Robust Sidelobe Cancellation Algorithm Based on Beamforming Vector Norm Constraint

Algorithm 2

Robust SLC algorithm with approximated Lagrange multiplier.

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: Calculate using Equation (28) and (29).

Step 4: Use Equation (17) to calculate .

Step 5: Use Equation (3) to calculate SLC output signal.
